Preparation of sulphenamidines. X-Ray crystal structure of N1,N1-dimethyl-N2-methylthiobenzamidine
Abstract
Readily available 3-(α-dialkylaminobenzylidene)-1-alkylthiotriazenes, when stirred in dichloromethane solution with copper(I) cyanide catalyst, give good yields of (E)-sulphenamidines (a new class of compounds): the mechanism of this extrusion reaction is discussed and the structure of one of the sulphenamidines has been established.
