Description

Insekticid virksomme, heterocykliske estere Insecticidally active, heterocyclic esters

av substituerte cyklopropankarboksylsyrer. of substituted cyclopropane carboxylic acids.

Foreliggende oppfinnelse angår nye insekticid virksomme, heterocykliske estere av substituerte cyklopropankarboksylsyrer. The present invention relates to new insecticidally active, heterocyclic esters of substituted cyclopropane carboxylic acids.

Pyretrumekstrakter og syntetiske alletriner anvendes meget som insekticider ettersom de er hurtigvirkende og uskadelige for pattedyr. Deres anvendelse har imidlertid vært begrenset på grunn av at de er relativt kostbare i fremstilling. Pyrethrum extracts and synthetic allethrins are widely used as insecticides as they are fast-acting and harmless to mammals. However, their use has been limited due to the fact that they are relatively expensive to manufacture.

Foreliggende oppfinnelse har til hensikt å tilveiebringe nye og billige forbindelser som har utmerket insekticid virkning sammen-lignet med vanlige krysantemater, og som dessuten er uskadelige for pattedyr. The present invention aims to provide new and cheap compounds which have excellent insecticidal activity compared to ordinary chrysanthemums, and which are also harmless to mammals.

De heterocykliske estere av substituerte cyklopropankarboksylsyrer ifølge oppfinnelsen er kjennetegnet ved at de er tenylestere med den generelle formel: The heterocyclic esters of substituted cyclopropane carboxylic acids according to the invention are characterized in that they are tenyl esters with the general formula:

hvor er en metyl-, etyl-, allyl- eller benzylgruppe eller et halogenatom, idet den. nevnte benzylgruppen kan være substituert med en metylgruppe, R2 og R^ er individuelt hydrogen eller et halogenatom, R^ er et hydrogenatom eller en metylgruppe, R^ er en metyl- eller 2-metyl-1-propenylgruppe, idet R^ ikke kan bety en 2-metyl-l-propenylgruppe når R^ er en metylgruppe. where is a methyl, ethyl, allyl or benzyl group or a halogen atom, wherein said benzyl group may be substituted with a methyl group, R2 and R^ are individually hydrogen or a halogen atom, R^ is a hydrogen atom or a methyl group, R^ is a methyl or 2-methyl-1-propenyl group, R^ cannot mean a 2-methyl-1-propenyl group when R 1 is a methyl group.

Fra norsk patent nr. 118 155 er* det kjent beslektede substituerte furanforbindelser med insekticid virkning. Forbindelsene ifølge oppfinnelsen som er tiofenderivater, har imidlertid en insekticid virkning som er langt bedre og mer fordelaktig enn den til de kjente forbindelsene. Related substituted furan compounds with insecticidal action are known from Norwegian patent no. 118 155. The compounds according to the invention, which are thiophene derivatives, however, have an insecticidal effect which is far better and more advantageous than that of the known compounds.

Man har funnet at forbindelser med den generelle formel (I) har utmerket insekticid virkning ikke bare overfor vanlige skadeinsekter i hus og i sanitære anlegg, men også generelt overfor skadeinsekter i jordbruket. It has been found that compounds of the general formula (I) have excellent insecticidal activity not only against common pests in houses and in sanitary facilities, but also generally against pests in agriculture.

Forbindelser ifølge foreliggende oppfinnelse fremstilles ved å forestre tenylalkoholer med den generelle formel: hvor R^, R2 og R^ har samme betydning som angitt ovenfor, med cyklopropankarboksylsyrer med den generelle formel: Compounds according to the present invention are prepared by esterifying tenyl alcohols of the general formula: where R^, R2 and R^ have the same meaning as stated above, with cyclopropane carboxylic acids of the general formula:

hvor R^ og R^ har samme betydning som nevnt ovenfor► Forbindelsene kan følgelig fremstilles enten ved å omsette alkoholene med den generelle formel (II) med karboksylsyrene med den generelle formel (III), eller where R^ and R^ have the same meaning as mentioned above► The compounds can therefore be prepared either by reacting the alcohols of the general formula (II) with the carboxylic acids of the general formula (III), or

halogenidene eller anhydridene av nevnte syre, eller ved å omsette halogenidene av alkoholene med den generelle formel (II), dvs. tenyl-halogenidene, med karb_^oksylsyrer med den generelle formel (III). Mesteparten av tenylålkoholene med den generelle formel (II) er nye forbindelser. De kan fremstilles ved å redusere de tilsvarende alde-hyder, karboksylsyrer eller estere av disse, ifølge vanlige fremgangs-måter ved å bruke metallhydrider eller lignende. De kan også med lett-het fremstilles ved en hydrolyse av halogenidene eller estrene av nevnte tenylalkoholer. Reaksjonen mellom tenylålkoholene og cyklopropan-karboksylsyrehalogenidene utføres i nærvær av et syrebindende middel, og reaksjonen utføres fortrinnsvis ved eller under romtemperatur. Anvendelsen av et inert oppløsningsmiddel er ikke kritisk, men det er å foretrekke for at reaksjonen skal gå glatt. Som syrebindende middel er det foretrukket å anvende en organisk tertiær base, men man kan og-så anvende et karbonat eller lignende av et alkalimetall eller et jord-alkalimetall. the halides or anhydrides of said acid, or by reacting the halides of the alcohols of the general formula (II), i.e. the phenyl halides, with carboxylic acids of the general formula (III). Most of the tenyl alcohols with the general formula (II) are new compounds. They can be produced by reducing the corresponding aldehydes, carboxylic acids or esters thereof, according to usual procedures using metal hydrides or the like. They can also be easily prepared by hydrolysis of the halides or esters of the mentioned tenyl alcohols. The reaction between the tenyl alcohols and the cyclopropane carboxylic acid halides is carried out in the presence of an acid-binding agent, and the reaction is preferably carried out at or below room temperature. The use of an inert solvent is not critical, but it is preferable for the reaction to proceed smoothly. As an acid-binding agent, it is preferred to use an organic tertiary base, but you can also use a carbonate or the like of an alkali metal or an alkaline earth metal.

Reaksjonen mellom halogenidene av alkoholene med den generelle formel (II), dvs. tenylhalogenider med den generelle formel: The reaction between the halides of the alcohols of the general formula (II), i.e. phenyl halides of the general formula:

hvor R^, R^ og R^ har samme betydning som nevnt ovenfor, og hvor X er et halogenatom, og de ovennevnte karboksylsyrer utføres i nærvær av et basisk kondensasjonsmiddel. I ovennevnte reaksjon er anvendelsen av et oppløsningsmiddel ikke kritisk, men det er ønskelig å anvende et inert oppløsningsmiddel som aceton eller metylisobutylketon for å få en jevn reaksjon. Som det basiske kondensasjonsmiddel kan man anvende en tertiær organisk base.som trietylamin, pyridin eller dietylanilin, eller et hydroksyd eller et karbonat av et alkalimetall eller et jord-alkalimetall. Hvis man anvender en tertiær organisk base, så kan denne på forhånd omsettes med halogenidet eller karboksylsyren, men det er mer fordelaktig å blande og omsette de tre forbindelsene samtidig. Hvis man på den annen side anvender et uorganisk hydroksyd eller karbonat, så kan de tre forbindelser blandes og omsettes samtidig, men det er mer fordelaktig på forhånd å omsette nevnte salt med karboksylsyren, slik at det dannes et syresalt. where R^, R^ and R^ have the same meaning as mentioned above, and where X is a halogen atom, and the above-mentioned carboxylic acids are carried out in the presence of a basic condensing agent. In the above reaction, the use of a solvent is not critical, but it is desirable to use an inert solvent such as acetone or methyl isobutyl ketone to obtain a uniform reaction. As the basic condensing agent, a tertiary organic base such as triethylamine, pyridine or diethylaniline, or a hydroxide or carbonate of an alkali metal or an alkaline earth metal can be used. If a tertiary organic base is used, this can be reacted beforehand with the halide or the carboxylic acid, but it is more advantageous to mix and react the three compounds at the same time. If, on the other hand, an inorganic hydroxide or carbonate is used, the three compounds can be mixed and reacted at the same time, but it is more advantageous to react the aforementioned salt with the carboxylic acid in advance, so that an acid salt is formed.

Når nevnte cyklopropankarboksylsyreestere med den generelle formel (I) fremstilles ved å omsette tenylålkoholene med den generelle formel (II) med anhydridene av karboksylsyrene ved den generelle formel (III), er det fordelaktig for å forkorte, reaksjonstiden å utføre reaksjonen med tilbakeløpskoking ved- en forhøyet temperatur i et inert oppløsningsmiddel som toluen eller xylen, skjønt reaksjonen også går ved romtemperatur. When said cyclopropane carboxylic acid esters of the general formula (I) are prepared by reacting the thenyl alcohols of the general formula (II) with the anhydrides of the carboxylic acids of the general formula (III), it is advantageous to shorten the reaction time to carry out the reaction with reflux by elevated temperature in an inert solvent such as toluene or xylene, although the reaction also takes place at room temperature.

Reaksjonen mellom tenylålkoholene med den generelle formel (II) og karboksylsyrene med den generelle formel (III) går lett og jevnt ved romtemperatur i nærvær av et dehydratiseringsmiddel som di-cykloheksylkarbodiimid, fortrinnsvis i et inert oppløsningsmiddel som metylenklorid, benzen eller toluen. The reaction between the tenyl alcohols of the general formula (II) and the carboxylic acids of the general formula (III) proceeds easily and evenly at room temperature in the presence of a dehydrating agent such as dicyclohexylcarbodiimide, preferably in an inert solvent such as methylene chloride, benzene or toluene.

Blant tiofenderivatene ifølge oppfinnelsen er det en del som har forskjellige stereoisomere former. Det er imidlertid underfor-stått at alle stereoisomere former med den generelle formel (I) om-fattes av foreliggende oppfinnelse. Among the thiophene derivatives according to the invention, some have different stereoisomeric forms. However, it is understood that all stereoisomeric forms with the general formula (I) are covered by the present invention.

Bortsett fra pyretrumekstrakter (som inneholder pyretrin) eller syntetiske alletriner som er homologe med den aktive bestanddel i nevnte py_retrumekstrakter og de furanestere av cyklopropankarboksylsyrer som er kjent fra norsk utleghingsskrift nr. 118 155, finnes det for tiden ingen tilgjengelige insekticider som ér hurtigvirkende, uskadelige overfor pattedyr og som kan brukes uten bekymring. Til tross for sin store anvendbarhet, har imidlertid pyretrumekstrakter og lignende forbindelser hatt en begrenset anvendelse på grunn av at de er relativt kostbare. Apart from pyrethrum extracts (which contain pyrethrin) or synthetic allethrins which are homologous to the active ingredient in said pyrethrum extracts and the furan esters of cyclopropane carboxylic acids which are known from Norwegian explanatory document no. 118 155, there are currently no available insecticides which are fast-acting, harmless to mammals and which can be used without concern. However, despite their wide utility, pyrethrum extracts and similar compounds have had limited application due to their relatively high cost.

I motsetning til pyretriner, alletriner og lignende forbindelser som inneholder krysanteminsyreestere som aktive bestanddeler, kan tiofenderivatene ifølge foreliggende oppfirineise fremstilles med lave omkostninger, og de er like effektive som insekticider av krysantemat-typen, idet de ikke bare viser insekticid virkning overfor skade-lige husinsekter som fluer, mygg, kakerlakker o.l., men også har lav toksisitet overfor pattedyr. In contrast to pyrethrins, allethrins and similar compounds containing chrysanthemic acid esters as active ingredients, the thiophene derivatives according to the present invention can be produced at low cost, and they are as effective as chrysanthemum-type insecticides, in that they not only show insecticidal activity against harmful house insects such as flies, mosquitoes, cockroaches etc., but also has low toxicity towards mammals.

Insekticide preparater som inneholder foreliggende tiofenderivater, representert ved den generelle formel (I), som aktive bestanddeler, er følgelig spesielt godt egnet for å hindre epidemier. I tillegg til dette har nevnte preparater utmerket insekticid virkning overfor skadeinsekter som angriper lagret korn, grønnsaker og ved, og de kan følgelig brukes for å hindre angrep av disse insekter eller å utrydde disse. På grunn av sin meget lave toksisitet kan nevnte preparater fritt brukes på nyttevekster, i drivhus eller i forbindelse med forpakningsmateriale for matvarer. Insecticidal preparations containing the present thiophene derivatives, represented by the general formula (I), as active ingredients, are consequently particularly well suited for preventing epidemics. In addition to this, said preparations have excellent insecticidal action against harmful insects that attack stored grain, vegetables and wood, and they can consequently be used to prevent attacks by these insects or to eradicate them. Due to their very low toxicity, the preparations mentioned can be freely used on crops, in greenhouses or in connection with packaging material for food products.

Av de forbindelser som er representert ved ovennevnte generelle formel (I), så er de som er nevnt i ovennevnte eksempler spesielt anvendelige for oppfinnelsens hensikt. Of the compounds represented by the above-mentioned general formula (I), those mentioned in the above-mentioned examples are particularly applicable for the purpose of the invention.
