ABSTRACT OF THE DISCLOSURE
Organic phosphoric acid esters of the formula

Description

r ~ _~
.~,..... .

~o47~B5 ~ The present invention relates to organic phosphoric . ., ~; acid esters, processes for their manufacture, and to their use in pest control.
:
~ The compounds have the formula ...~, ,~,:
~ ., ~s,' ~
. .
; ~ N=N ~ ~ O P / I (I) (R4)m (R3)n wherein Rl and R2 each represents alkyl with 1 to 5 carbon atoms, R3 and R4 each represents halogen or alkyl with 1 to 5 carbon atoms, X represents oxygen or sulphur, n is zero or a number from 1 to 4, and m is zero or a number from 1 to 5.

:., By halogen is meant fluorine, chlorine, bromine, or iodine, but especially chlorine or bromine.
~' i The alkyl group Rl to R4 can be straight-chain or branched.
:
Examples of such groups include: methyl, ethyl, propyl, iso-~;~ propyl, n-, i-, sec.- and tert.-butyl, n-pentyl and isomers thereof.

~ In the formulae II to VIII, to R4, n and m have the : meanings given for the formula I, Hal represents a halogen atom, in particular chlorine J and Me represents an alkali metal, -. especially sodium or potassium, an ammonium or alkylammonium group.

. . . - . .

n47~89 Suitable acid acceptors are: tertiary amlnes, e.g. trial-kylamine, pyridine~ dialkyl anilines; inorganic bases, e.g.
hydrides, hydroxides; carbonates and bicarbonates o-f alkali metals and alkaline earth metals. It is sometimes necessary to use catalysts in the reac~ions, for example copper or copper chloride. Processes laJ lb, and 2 are carried out at a reac-tion temperature between -2C and 130''C, at normal pressure, and in solvents or diluents.

Examples of suitable solvents or diluents are: e~her and ethereal compounds, e.g. diethyl e~her, dipropyl ether, dioxan tetrahydrofuran; amides, e.g. N,N-dialkylated carboxylic acid amides; aliphatic, aromatic, and halogenated hydrocarbons, in ~.
particular benzene, tuolene, xyleneJ chloroform, chloroben~ene;
nitriles, e.g. acetonitrile; dimethyl sulphoxide; ketones, e.g. acetone,methyl ethyl ketone; water.

The starting materials of the formulae II, III, IV, V, VII, and VIII can be manufactured in an~logous ~anner to known methods.

The compounds of the formula I have a broad biocidal act-ivity spectrum and can therefore be used for combating various plant and animal pests. In particular they are suitable for combating insects of the families: Acrididae, Blattidae, ~r~oc-10 ~ . Gryllidae, Gryllotalpidae, Tettigoniidae, Cimicidae, PLl~rrhoc oridae, Reduviidae, Aphididae, Delphacidae, Diaspididae, Pseu-doccidae, Chrysomalidae, Coccinellidae, Bruchidae, Scara~aei-dae, Dermestidae, Tenebrionidae, Curcu ionidae, Tineidae, Noctuidae, Lymantriidae, Pyralidae, Galleriidae, Culicidae, Tipulidae, Stomoxydae, Musci~ae, Calliphoridae, Trypetidae, ., , _ 4 Pulicidae J as well as Acaridae of the families: Ixodidae, Argasidae 9 Tetranychidae, Dermanyssidae. ~ -By addit;on of other insecticides and/or acaricides it ~ -- is possible to improve substan~ially the insecticidal or acaricidal action and to adapt it to given circumstances.
The follo~Jing active substances are examples of suitable ~, , additives:
