title: The reactions of cyclization of semicarbazide derivatives of 1,3-diphenyl-1,2,4-triazolin-5-thione-4-acetic acid.
abstract: In the reaction of hydrazide of 1,3-diphenyl-1,2,4-triazolin-5-thione-4-acetic acid with isocyanates. semicarbazide derivatives of 1,3-diphenyl-1,2,4-triazolin-5-thione-4-acetic acid [I-X] were obtained. Cyclization of these compounds in the presence of 2% NaOH led to the formation of derivatives of 1,2,4-triazolin-5-one [XI-XX].
