摘要

Jan. 1981 Amidrazones. 6 (1). Synthesis of 1,2,4-Thiadiazoles by Thermolysis of N3-Thiocarbamoylamidrazone Ylides Richard F. Smith * and Timothy P. Feltz Departmrnt of Chemlstry, Statr University, College of Arts and Srienrr, Geneseo, N. Y. 14454 Rrceived July 28, 1980 ... Reaction of N3-unsubstituted aniidrazone ylides (la and lb) with alkyl or aryl isothiocyanates gives N3-thiocarbamoylamidrazone ylides (2). Thermolysis of 2 gives 3-alkyl(or aryl)-5-alkyl(or aryl)amino-1,2,4- thiadiazoles ...
