The reaction of various heterocyclic cation compounds with I2/NH4OH resulted in ring expansion on nitrogen atom.The similar ring expansion reaction occured on the corresponding triiodides with NH4OH.The reaction mechanism based on initial nucleophilic att

2-Substituted 1,3-dithiol-2-yl azides, on thermolysis in refluxing toluene, give 3-substituted 1,4,2-dithiazines wich thermally extrude sulfur atom of the 4-position selectively to yield 3-substituted isothiazoles, while 2-unsubstituted 1,3-dithiol-2-yl azides undergo both ring expansion yielding 1,4,2-dithiazines and peculiar thermal dissociation into 1,3-dithiol-2-ylidene carbenes and hydrogen azide.
