Compounds of Formulae I, II and III can be prepared by the reaction of a pyrazoline compound of Formula V, VI or VII with a sulfenyl halide of

Formula IV.

wherein

Y in Formula IV represents a halogen such as

chloro, bromo, or iodo.

The treatment of V, VI or VII with IV is carried out by mixing the two reagents in the presence of a base and a solvent. Suitable bases are the tertiary amines εuch as triethylamine or pyridine. Alkali metal bases such as sodium hydride or potassium tert-butoxide or organo lithium bases such as aryl or alkyllithium also can be utilized.

Suitable solvents include methylene chloride, tetrahydrofuran or ether. In some cases, the base can alεo be used as the solvent, e.g., pyridine. In most cases, it is desirable to mix compounds of Formula V, VI or VII and the desired base at a low temperature of about 5 °C to -70 °C which is held at this temperature during treatment with the appropriate amount of compounds of Formula IV. The mixture is then warmed to room temperature to complete the reaction.

Generally, it is desirable to employ a moderate stoichiometric excess, up to 10% of the base and compounds of Formula IV relative to compounds of Formula V, VI or VII. Water should be excluded from the reaction mixture by using anhydrous reagents and conducting the treatment in a nitrogen atmosphere. The product is isolated and purified by conventional techniques as demonstrated in Example 1. The pyrazoline precursors of Formula V, VI, and VII are compounds that can be prepared by methods known to those skilled in the art. The methods of pyrazoline synthesis have been recently reviewed by El-Rayyes and Al-Awadi in "Synthesis" page 1028 to 1042, November 1985.

Compounds of Formula V wherein B=H can be prepared by the following sequence of reactions as shown in Scheme 1.

In another embodiment, certain compounds of Formula V wherein B is other than H can be prepared directly from compoundε of Formula V wherein B is H by further treatment with a base and the appropriate type of electrophile as illustrated by Scheme 2.

SCHEME 2

V v

(B is H) 2. electrophile (B is other than H, phenyl, or substituted phenyl)

Compounds of Formula V where B is also phenyl or substituted phenyl can be prepared by reaction of a substituted ketone of Formula X with hydrazine as shown in Scheme 3.

SCHEME 3

For compounds of Formula VI, Grosscurt et al., have published the synthesis of 3,4-diphenyl-1-phenyl- carbamoyl-2-pyrazolines in Journal of Agricultural and Food Chemistry, 27:406-409 (1979). Similar methods of synthesis are also presented in U.S.

4,633,341. Compounds of Formula VII have been

prepared using procedures indicated in PCT

WO 88/05046. Sulfenyl halides of the type XSY (Formula IV) wherein X and Y are as specified in this disclosure are known in the literature. A review article by Kule in Synthesis, 561, (1970) describes the

chemistry and preparation of the majority of sulfenyl halides utilized in this invention. The synthesis of N-chlorosulfenylcarbamates was described in U.S.

3,843,689. Other sulfenyl halides can be prepared by the general procedures described in these literature examples or obvious modifications thereof.

Compounds of Formula I (Q is other than SX) are synthesized from compounds of Formula VI.

Reaction of compounds of Formula VI in the presence of an acid acceptor with electrophilic

carbonyl-containing reagents results in substitution on nitrogen. Strong bases known to deprotonate ureas such as potassium t-butoxide, potassium hydride and sodium hydride are the preferred acid acceptors in the process. Suitable electrophiles include, but are not restricted to , acyl halides, acid anhydrides, carbonates, and chlorof ormates. The reaction

sequence is normally run in the temperature range of -10 to 25°C, but can be run at temperatures as high as 110°C or as low as -50°C in certain cases.

Solvents which are not deprotonated under the

conditions of the reaction such as tetrahydrofuran, dimethylformamide, dimethoxyethane, and diethyl ether

are preferred. The electrophiles used in this process are well known to those skilled in the art and are generally commercially available.

To this was added a solution of 45.93 g of the sulfonate from Step A and the mixture was then heated at reflux overnight. The reaction was then cooled to room temperature, poured into 400 ml of IN HCl, and extracted with ether. The ether extracts were dried over magnesium sulfate, filtered and concentrated under reduced pressure to afford 68.9 g of a yellow oil. The crude oil was dissolved in 400 ml of methanol, 100 ml of H₂O and 40 ml of 50% aqueous NaOH. The reaction was stirred overnight and the methanol was then removed at reduced pressure. The crude reεidue was partitioned between H₂O and ether, the aqueous extracts were acidified with concentrated HCl and then extracted several times with ether. The ether extracts were dried over magne- sium sulfate, filtered and concentrated to afford 51.7 g of a yellow oil. The crude reεidue was disεolved in 200 ml of toluene and heated at reflux for 4 days under N₂ to effect decarboxylation. After this time toluene was removed by concentration at reduced preεsure to afford 35.72 g of a yellow oil. ¹H NMR analysis of the crude product was consistent with 3-chlorobenzene- butenoic acid of purity estimated to be 80%. The crude product was used without further purification directly in the next step.

Step C: 6-chloro-3,4-dihydro-1(2H)-naphthalenone

A mixture of 35.72 of the product from Step B and 50 ml of thionyl chloride was heated at reflux for 2 hours and then stirred at room temperature for 18 hours. After this time thionyl chloride was removed at reduced pressure and the product was dissolved in carbon tetrachloride and concentrated at reduced pressure. The residue was dissolved in 150 ml of dichloroethane cooled to 0°C and 28 g of aluminum chloride waε added portionwise over about 1 hr in approximately 3 g portions. After stirring for 3 hrs the reaction was poured over a mixture of ice/lN HCl and extracted three times with methylene chloride. The organic extracts were dried over magnesium sulfate and concentrated to approximately 30 g of a brown oil. Chromatography on silica gel with 10% ethyl acetate/hexane afforded 17.83 g of 6-chloro-3,4-dihydro-1(2H)-naphthalenone as a brown oil. ¹H NMR was consistent with the structure.

Step D: 7-chloro-3,3a,4-5-tetrahydro-N-[4-(trifluoromethyl)phenyl]-2H-benz[g]-indazole- 2-carboxamide

A mixture of 6-chloro-3,4-dihydro- 1(2H)-naphthalenone (Step C), 2.5 g of dimethylamine hydrochloride, 1.0 g of paraformaldehyde, 0.7 ml of concentrated HCl and 15 ml of ethanol was combined and heated at reflux for 18 hrs. The reaction was then concentrated at re- duced presεure and

partitioned between H₂O and ether. The aqueouε extractε were made baic with IN NaOH and then

extracted three times with ether. The ether extracts were dried over magnesium sulfate and concentrated to 4.64 g of a yellow oil. This compound waε dissolved in 25 ml of ethanol and 1.5 ml of hydrazine hydrate was added followed by 5 to 6 drops of 50% sodium hydroxide. The reaction was then heated at reflux, under N₂, for 2 to 3 hrs after which time it was cooled and most of the ethanol was removed by concentration at reduced pressure. The crude residue was partitioned between saturated aqueous sodium bicarbonate and methylene chloride. The methylene chloride extracts were dried over magnesium sulfate and filtered. The methylene chloride extracts were then combined with 3.5 g of 4-trifluoromethylphenyl isocyanate and stirred under N₂ overnight. The reaction was then concentrated and the crude residue triturated with ether to afford 3.35 g of the title compound as a white powder, m.p. 196 to 199°C.

Step E: 7-chloro-3,3a,4,5-tetrahydro-3a-methoxy- carbonyl-N-[4-(trifluoromethyl)phenyl]- 2H-benz[g]indazole-2-carboxamide

A solution of 50 ml of THF and 6.7 ml of diisopropylamine waε cooled under N₂ to -78°C and then 17.5 ml of 2.5 M n-butyllithium in hexane was added. After 5 min, a solution of 7.8 g of the title compound of Step D in 15 ml of THF was added dropwise and the dark red solution that formed was stirred at -78°C for an additional 15 min. After this time a εolution of 4.6 ml of methyl chloroformate in 10 ml of THF was added dropwise and the red color

dissipated rapidly. The reaction was warmed to room temperature and after 1 hr quenched with 5% aqueous sodium bicarbonate. The reaction mixture was partitioned between ether and 5% aqueous sodium bicarbonate. The ether extracts were dried over magnesium sulfate and concentrated to 14.1 g of a yellow oily solid. The crude product was triturated with ether and the resulting white precipitate was filtered and dried to afford 5.56 g of the title compound as a white solid, m.p. 234 to 236°C.

To a suspension of the title compound of Step E above (2.2 g, 0.005 mol) in 25 ml methylene

chloride cooled to 0°C was added triethylamine (1.0 g) and hexyl (chlorosulfenyl) (methyl)carbamate,

(prepared in a manner similar to Example 1, Step D), (2.5 g 75% pure) dropwise at 0°C. The mixture was stirred at room temperature for additional one hour. The reaction mixture was concentrated under high vacuum and subjected to silica gel column

chromatography using hexane-ether (1:1) as an

eluent. The title compound (2.5 g) was obtained, melting point 128-129°C in high purity.

Formulation and Use

The compounds of this invention will generally be used in formulation with a carrier comprising a liguid or solid diluent or an organic solvent.

Useful formulations of the compounds of this

invention are prepared in conventional ways. They include dusts, baits, traps, granules, pellets,

solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates, dry flowables and the like. Many of thes can be applied directly.

Sprayable formulations can be extended in suitable media and used at spray volumes of from about one to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 1% to 99% solid or liquid diluent(s). More specifically, they will contain these

ingredients in the following approximate proportions:

Percent by Weight

Active

Ingredient Diluent(s) Surfactant (s)

Wettable Powders 25-90 0-74 0-10

Oil Suspensions, 1-50 40-95 0-35

Emulsions, Solutions

(including Emulsifi- able Concentrates)

Dusts 1-25 70-99 0-5

Granules, Baits 0.01-95 5-99 0-15

and Pellets

High Strength 90-99 0-10 0-2

Compositions Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound.

Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing.

Typical solid diluents are described in

Watkins, et al., "Handbook of Insecticide Dust

Diluents and Carriers," 2nd Ed., Dorland Books,

Caldwell, New Jersey. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide," 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0°C. "McCurcheon's Detergents and

Emulsifiers Annual," Allured Publ. Corp., Ridgewood, New Jersey, as well as Sisely and Wood, "Encyclopedia of Surface Active Agents," Chemical Publ. Co., Inc.,

New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth, etc. Preferably, ingredients should be approved by the U.S. Environmental Protection Agency for the use intended.

The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, griding as in a hammer or fluid energy mill. Suspensions are prepared by wet-milling (see, for example, U.S. 3,060,084). Granules and pellets can be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See Browning, "Agglomeration," Chemical Engineering, December 4, 1967, pages 147 and following, and "Perry's Chemical Engineer's Handbook," 4th Ed., McGraw-Hill, New York, 1963, pages 8 to 59 and following.

Many of the compounds of the invention are most efficacious when applied in the form of an emulsifiable concentrate mixed with a spray oil or spray oil concentrate. Although any oil can be used as a spray oil, spray oils usually have these characteristics: they are not phytotoxic to the crop sprayed, and they have appropriate viscosity. Petroleum based oils are commonly used for spraying. In some areas, crop oils are preferred such as the following:

Common Crop Oils Used as Spray Oils

Corn Oil Linseed Oil

Cottonseed Oil Soybean Oil

Coconut Oil Sunflower Oil

Rapeseed Oil Olive Oil

Peanut Oil Palm Oil

Safflower Oil Sesame Oil

Mustardseed Oil Castor Oil

The following oils also meet the criteria for a spray oil: mineral, fish and cod liver oil. Spray oil concentrates comprise a spray oil together with one or more additional ingredients such as emulsifiers and wetting agents. A number of useful spray oil and spray oil concentrates can be found in "A Guide to Agricultural Spray Adjuvants Used in the United States" by Thomson, Thomson Publications, California, 1986.

Utility

The compounds of the present invention exhibit activity against a wide spectrum of foliar and soil-inhabiting, livestock, household and public health arthropods. Those skilled in the art will recognize that not all compounds will be equally effective against all arthropods but the compounds of this invention display activity against economically important pest species, such as grasshoppers and cockroaches including German or American roaches;

thrips; hemipterans: plant bugs (Miridae)

such as tarnished plant bugs, lace bugs (Tingidae), seed bugs (Lygaeidae) such as cinch bugs, stink bugs (Pentatomidae), leaf-footed bugs (Coreidae) such as squash bug, and red bugs and stainers (Pyrrocoridae) such as cotton stainer; also homopterans such as whiteflies, aphids such as the green peach aphid, greenbug and cotton aphid, leafhoppers, spittlebugs and planthopperε such as aster leafhopper, potato leafhopper and rice planthoppers, psyllids such as pear psylla, scales (coccids and diaspidids) and mealybugs; coleopterans including weevils such as boll weevil and rice, water weevil, grain borers,

chrysomellid beetles such as Colorado potato beetle, flea beetles and other leaf beetles, coccinellid beetles such as Mexican bean beetle. Activity is also shown against soil insects such as southern corn rootworm and wireworm;

lepidopterous larvae including noctuids such as fall armyworm, beet armyworm, other Spodoptera spp.,

Heliothis spp. such as virescens, Heliothis zea, cabbage looper, green cloverworm, velvetbean

caterpillar, cotton leafworm, black cut- worm, and other noctuid cutworms and including pyralids such as European corn borer, navel orange- worm, and

stalk/stem borers and including tortricids like codling moth and grape berry moth as well as other lepidopterous larvae such as pink bollworm

and diamodback moth; and dipterans such as leafminer, soil maggots, midges, and tephritid fruit flies; house fly, Musca domestica; stable fly,

Stomoxys calcitrans; black blow fly, Phormia regina; face fly, Musca autumnalis; black fly, Simulum

meridionale: yellow fever mosquito, Aedes egypti;

German cockroach, Blattella germanica; carpenter ants, Camponotus pennsylvanicus and eastern subterranean termite, Reticulitermes flavipes. The pest control afforded by the compounds of the present invention is not limited, however, to these species.

The specific species, for which control is exemplified below, are: fall armyworm, Spodoptera frugiperda; tobacco budworm, Heliothis virescens;

southern corn rootworm, Diabrotica undecimpunctata howardi; aster leafhopper, Macrosteles fascifrons. The pest control afforded by the compounds of the present invention is not limited, however, to these species. Application

Arthropods are controlled in agricultural crops and animals and humans are protected by applying one or more of the compounds of this invention, in an effective amount, to the locus of infestation, to the area to be protected, directly to the pests to be controlled, or to their environment. A preferred method of application is by spraying with spray equipment that distributes the compound on the

foliage, in the soil, or to the plant part that is infested or needs to be protected. Alternatively, granular formulations of these compounds can be applied to soil or foliage or, optionally,

incorporated into the soil. Either aerial or ground application can be used. Because of the diversity of behavior patterns and habitats of the anima l and human health species, many different methods of application are employed. These include direct and residual sprays, baits, ear tags, soil treatment and many others.

The pyrazoline compound(s) of this invention can be applied directly, but most often application will be of a formulation comprising one or more compounds of this invention, in an agriculturally suitable carrier or diluent. A most preferred method of application involves spraying a water dispersion or refined oil solution of the compounds. The

compound(s) can also be mincorporated into baits which are consumed or in devices such as traps and the like that entice the arthropod to ingest or otherwise contact the toxicant compound(s).

The rate of application of Formula I, II or III compounds required for effective control will depend on such factors as the species of arthropod to be controlled, the pest's life stage, its size, its location, the host crop, time of year of application, ambient moisture, temperature conditions, and the like. In general, application rates of 0.01 to 2 kg of active ingredient per hectare are sufficient to provide effective control in large scale field operations under normal circumstances, but as little as 0.001 kg/hectare may be sufficient or as much as 8 kg/hectare may be required for agricultural use, or 0.1 mg/ft² to 20 mg/ft² for home use, depending upon the factors listed above.

The following Examples demonstrate the control efficacy of compounds of Formulae I, II and III on specific arthropod pests wherein Compounds 1 through 55 are depicted in the Examples and Tables A, B and C and summarized in Table D, respectively.

Example 56

Fall Armyworm

Test units, each consisting of an 8-ounce plastic cup containing a layer of wheat germ diet, approx. 0.5 cm thick, were prepared. Ten

third-instar larvae of fall armyworm (Spodoptera frugiperda) were placed into each cup. Solutions of each of the test compounds (acetone/distilled water 75/25 solvent) were sprayed onto the cups, a single solution per set of three cups. Spraying was

accomplished by passing the cups, on a conveyor belt, directly beneath a flat fan hydraulic nozzle which discharged the spray at a rate of 0.5 pounds of active ingredient per acre (about 0.55 kg/ha) at 30 p.s.i. The cups were then covered and held at 27C and 50% relative humidity for 72 hours, after which time mortality readings were taken.

Of the compounds tested on fall armyworm, the following resulted in greater than or equal to 80% mortality: 1, 2, 4, 5, 6, 7, 9, 10, 11, 12, 13, 16, 17, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 35, 36, 38, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, and 54.

Example 57

Tobacco Budworm

The test procedure of Example 56 was repeated for efficacy against third-instar larvae of the tobacco budworm (Heliothis virescens) except that mortality was assessed at 48 hours. Of the compounds tested on tobacco budworm, the following resulted in greater than or equal to 80% mortality: 2, 4, 7, 11, 16, 17, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 35, 36, 38, 41, 42, 43, 44, 45, 46, 48, 49, 50, 51, 52, 53 and 54. Example 58

European Corn Borer

Test units, each consisting of an 8-ounce plastic cup containing a one-inch square of wheat germ/soyflour diet, were prepared. Five third-instar larvae of the European corn borer (Ostrinia nubilalis) were placed into each cup. Sets of three test units were sprayed as described in Example 56 with individual solutions of the test compounds. The cups were then covered and held at 27C and 50% relative humidity for 48 hours, after which time mortality readings were taken. Of the compounds tested on

European corn borer, the following resulted in

greater than or equal to 80% mortality: no testing.

Example 59

Southern Corn Rootworm

Test units, each consisting of an 8-ounce plastic containing 1 sprouted corn (Zea mays) see, were prepared. Sets of three test units were sprayed as described in Example 56 with individual solutions of the test compounds. After the spray on the cups had dried, five third-instar larvae of the southern corn rootworm (Diabrotica undecimpunctata howardi) were placed into each cup. A moistened dental wick was inserted into each sup to prevent drying and the cups were then covered. The cups were then held at 27C and 50% relative humidity for 48 hours, after which time mortality readings were taken.

Of the compounds tested on southern corn rootworm, the following resulted in greater than or equal to 80% mortality: 1, 2, 3, 4, 6, 7, 9, 10, 11, 13, 16, 17, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 35, 36, 38, 41, 42, 44, 45, 47, 48, 49 and 51. Example 60

Aster Leafhopper

Test units were prepared from a series of 12-ounce cups, each containing oat (Avena sativa) seedlings in a 1-inch layer of sterilized soil. Sets of three test units were sprayed as described in

Example 56 with individual solutions of the belowlisted compounds. After the oats had dried from the spraying, between 10 and 15 adult aster leafhoppers (Mascrosteles fascifroms) were aspirated into each of the cups. The cups were held at 27C and 50% relative humidity for 48 hours, after which time mortality readings were taken.

Of the compounds tested on aster leafhopper, the following resulted in greater than or equal to 80% mortality: 1, 2, 3, 4, 6, 7, 8, 9, 10, 11, 12, 13, 16, 17, 19, 20, 21, 22, 23, 24, 25, 26, 28, 30, 31, 35, 36, 38, 41, 42, 43, 44, 45, 47, 49, 50 and 51.
