New N-alkyl(ene)-N-[(O,O-disubstituted)thiophosphoryl]glycine N',N'-disubstituted amides, process for their preparation and acaricide, insecticide and fungicide containing these compounds as active substance

摘要

N-Alkyl(ene)-N-[(O,O-disubstituted)thiophosphoryl]glycine N',N'-disubstituted amides of formula (I): in which: R1 and R2 represent a C1-4 alkyl group optionally substituted by one or more halogen atoms, a C2-6 alkenyl group, a C3-6 cycloalkyl group, a phenyl group or a (lower alkoxy)alkyl group, R3 represents a C1-6 alkyl group or C2-6 alkenyl group, R4 and R5 represent hydrogen, a C1-6 alkyl group, a C2-6 alkenyl group, a C3-6 cycloalkyl group, a phenyl group, a benzyl group, a phenyl group substituted by one or more C1-3 alkyl groups and/or by one or more halogen atoms, a (lower alkoxy)alkyl group, or a group of formula (CH2)n-R6, in which n is an integer of between 0 and 3, and R6 represents a saturated or unsaturated 3- to 7-membered ring comprising 1 to 3 heteroatoms chosen from N, O and/or S, and R4 and R5 can together form, with the adjacent nitrogen atom, a hexamethyleneimino group. The compounds of the invention have an acaricidal, insecticidal and fungicidal activity.
