Interaction of thermal acylacetylenes with thiosemicarbazide and 4-methyl- and 4-phenylthiosemicarbazides Academic Article uri icon

abstract

  • By the reaction of thiosemicarbazide and 4-methyl- and 4-phenylthiosemicarbazides with terminal a-acetylenic ketones, depending on the conditions, thiosemicarbazones of acylacetic aldehyde, 1,1-bis(acylvinyl)thiosemicarbazides,and5-phenylamino-2-acylmethyl-3-acylvinyl-1,3,4-thiadiazolinesareobtained. Ring-chain tautomerism of the 1,1-bis(acylvinyl)thiosemicarbazides has been investigated.
