Abstract
Thiorhodanine is recyclized to 1,2,4-triazole-3-thione by reaction with hydrazine. The intermediate recyclization products were identified. 4-Iminothiazolidone is recyclized to 1,2,4-triazol-3-one by reaction with hydrazine, 1,3-oxazolid-4-one-2-thione forms 2-hydrazonooxazolid-4-one by reaction with hydrazine in neutral solvents. The intermediate transformation products were isolated and indicate that the reaction proceeds as a recyclization of the starting oxazolidone under the influence of hydrazine.
