Formation of thiadiazole, thiadiazine, thiadiazepine and pyrazole derivatives in the reaction of 2,4-disubstituted thiosemicarbazides with tetracyanoethylene Open
The reaction of 2,4-disubstituted thiosemicarbazides with tetracyanoethylene gave mixtures of 1,3,4thiadiazole, 1,3,4-thiadiazine, 1,3,4-thiadiazepine and pyrazolidine derivatives.Rationale mechanisms for these transformations are presente…
