Abstract
The reaction of 3,5-diphenyl-1,2,4-dithiazol-1-ium perchlorate with several kinds of active methylenes gives a number of heterocycles, such as 4-hydroxy and 4-mercaptopyrimidine, pyrimidinone, and thiazole derivatives. On treatment with hydroxylamine-O-sulfonic acid, the 4-mercaptopyrimidines lead to the aminothio compounds or the isothiazolo[5,4-d]pyrimidine.
