Research on acyl isocyanates and their derivatives

1-Substituted benzimidazolinethiones, 3-substituted 1-acylbenzimidazolinethiones, and acyl thiobiurets, respectively, are formed in the reaction of acyl, alkyl, and aryl isocyanates with benzimidazolinethione, its 1-acyl derivatives, and thiourea. The IR and UV spectra of the compounds obtained are analyzed.See [1] for communication X.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 5, pp. 695–698, May, 1973.
