Abstract

Substituted ethanone oximes react with S2Cl2 and pyridine to give 1,2,3-dithiazolium chlorides. The treatment of these products with malonodinitrile in dichloromethane affords 4-substituted 5 H-1,2,3-dithiazol-5-ylidenes. The reaction of the latter compounds with n-butylamine unexpectedly yielded addition products at one of the nitrile groups, viz. substituted 1,2,3-dithiazol-5-ylideneethanimidamides.
