ABSTRACT:
There is described a process for producing N-chlorosulfenyl compounds of the formula ##STR1## in which R.sub.1 is alkyl, alkoxycarbonyl, alkoxycarbonylalkyl or 2,3-dihydro-2,2-dimethylbenzofuran-7-yloxycarbonyl, and R.sub.2 is alkyl or alkoxycarbonylalkyl, which process is based on the reaction of an amino compound of the formula ##STR2## with sulfur dichloride. The essential feature of the process is that the reaction of the amino compound of the above formula with the sulfur dichloride is performed in excess sulfur dichloride as solvent and in the absence of a base. The formed N-chlorosulfenyl compounds of the above formula are intermediates for insecticidal and acaricidal active substances.
