4-Phenyl-1,2-dithiolium perchlorate reacts with ammonia in ethanol to yield 4-phenyl-isothiazole. The reaction is general for dithiolium salts. When unsymmetrical dithiolium salts are treated with ammonia, the major product and, under many conditions, the only product is the 5-substituted isothiazole. Of the four possible mechanisms for these reactions, an addition-elimination mechanism has been shown

2-Alkylisothiazolium salts were prepared by quaternisation of the corresponding isothiazoles; they were found to be relatively stable to oxidation but when unsubstituted, formed insoluble complexes with heavy metal salts. The isothiazolium salts were decomposed by aqueous alkali, but were found to yield a series of products including both cyclic and acyclic compounds on treatment with a range of nitrogen
