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

The first example of application of sulfenamides for ring expansion on nitrogen atom has been reported to give 1,4,2,5-dithiadiazines (3) from 1,4,2-dithiazolium salts (1).The structure of 3 was confirmed by X-ray crystallographic analysis.The similar rin
