Reactions of S-alkyl-N,N-disubstituted thioamide salts. Part 4. Sulphenamidine derivatives

Abstract

Readily available 3-(α-dialkylaminoalkylidene)-1-alkylthiotriazenes (1) with C-aryl, benzyl, or isopropyl substituents, on being stirred with copper(I) cyanide or copper powder in dichloromethane or toluene solution at room temperature or below, give sulphenamidines (2) whose properties have been investigated. A mechanism for this extrusion reaction is suggested.
