Abstract

2-Trifluoromethylimino-benzo-heterocyclic compounds of the general formula ##SPC1## In which PA1 X is oxygen or sulfur, PA1 Y is oxygen, sulfur or the radical ##EQU1## R is lower alkyl, cycloalkyl, aryl, aryl substituted by at least one of halogen, nitro, methyl and methoxy, alkylcarbalkoxy with up to 6 carbon atoms, alkylsulfonyl, arylsulfonyl, dialkylamidosulfonyl, or --CO--R', PA1 R' is alkyl or alkoxy with up to 12 carbon atoms, aryl, amino, lower alkylamino, di-lower alkylamino, or arylamino, each Z independently is halogen, trifluoromethyl, nitro, lower alkyl, lower alkoxy, di-lower alkylamino, acyl with up to 6 carbon atoms, a sulfonic acid group, a sulfonic acid amide group, or a sulfonic acid amide group substituted by alkyl with up to 6 carbon atoms, and PA1 m is an integer from 0 to 4, Which possess fungicidal, insecticidal and acaricidal properties, and a process for their preparation wherein a compound of the general formula ##SPC2## Is reacted with perfluoroazapropene of the formula EQU F.sub.2 C=N-CF.sub.3 (III) in an aprotic solvent in the presence of a hydrogen fluoride acceptor.
