The reaction of thiocarbohydrazide with carbonylcontaining compounds ha-been reported by several authors investigating heterocyclic ring formation2-j and by those suggesting6 thnt thiocarbohydrazide be used as an analytical reagent Owing to the presence of the thiocarbonyl group however, t hiocarbohydrazones could be useful n- The work reported here was undertaken in order to investigate this possibility.
