N-acyl-derivatives with carboxylic anhydrides under various sets of conditions are shown to lead to 2-acylalkylidene-3-aryl-5-phenyl-2H-1,3,4-thiadiazolenes. The probable mechanism of formation of these compounds via the corresponding 2-alkylidenethiadiazolene as intermediate is discussed.

Prospective routes to the above compounds include reaction of an N′-arylbenzothiohydrazide or of its N′-acetyl derivative with thioacetic acid, when the thioacyl and acyl derivatives are formed, as well as by reaction of the 2-acylmethylene-3-aryl-5-phenyl-2H-1,3,4-thiadiazolenes with phosphorus pentasulphide. The 1H n.m.r. and mass spectra of these compounds are discussed.
上述化合物的预期途径包括当形成硫代酰基和酰基衍生物时,N'-芳基苯并硫酰肼或其N'-乙酰基衍生物与硫代乙酸的反应,以及通过2-酰基亚甲基-3-芳基-的反应。 5-苯基-2 H -1,3,4-噻二唑与五硫化二磷。讨论了这些化合物的1 H nmr和质谱。
