Carbamoyl sulfides of the formulae …<CHEM>… wherein… R is selected from various iminooxy groups;… R<1>, R<2>, R<3> and R<4> are independently H, halogen, nitro, CN, CF3, alkyl, alkoxy, ester or amide groups; or R<1> and R<2> form a butadienyl bridge;… R<1><1>, R<1><2>, R<1><3> and R<1><4> are independently H, alkyl, alkoxy or halogen; or either R<1><1> and R<1><2> or R<1><3> and R<1><4> form a butadienyl bridge;… exhibit insecticidal activity especially on Lepidoptera species. They may be formulated for use in conventional manner. …<??>The compounds can be made by reacting corresponding acyl fluorides of formulae …<CHEM>… with RH in the presence of base. …<??>The novel acyl fluorides from a further aspect of the invention. They may be made by reacting a corresponding 2- or 4-nitrosophenol with N,N min -thiobis[N-methylcarbamic fluoride]. |
