Preparation of the parent heterocycles, 1,4,2-dithiazole-5-thione, 1,4,2-dithiazol-5-one, and the 1,4,2-dithiazolium cation
Abstract
The first syntheses of the title parent heterocycles are described, using a sequence of steps involving common reagents; some spectroscopic data are given, together with evidence for charge delocalization in the 1,4,2-dithiazolium cation.
