Researches on 1, 2, 4-triazoles

A new method of preparing 1, 2, 4-triazolinethione derivatives by directly sulfurating the corresponding triazoles is described. 4-(-Pyridyl)-1, 2, 4-triazoline-3-thione undergoes aminomethylation, cyanoethylation, and pyridylethylation at the nitrogen of the thioamide group. Replacement of the phenyl group in 4-phenyl-1, 2, 4-triazolinethione by -pyridyl, gives a compound closely resembling 1-phenyltetrazoline-5-thione in its properties.For Part VII see [1].
