In the course of preparing some 1,2‐dialkyl‐4‐aryl‐5‐thioxo‐1,2,4‐triazolin‐3‐ones (III) (1), we were looking for a route which would eliminate the problem associated with (a) preparation of 1,2‐dialkyl hydrazines and (b) specificity in addition to the isothiocyanate or isocyanate when the alkyl groups were not the same.
