Zhang, Youming,Wei, Taibao,Lu, Jinren

, p. 3243 - 3248 (1998)

Reaction of hydrazine hydrate with aroyl chloride and ammonium thiocyanate under the condition of solid-liquid phase transfer catalysis using polyethylene glycol-600 (PEG-600) as the catalyst yielded 1,5- diaroyldithiohydrazodicarbonamides 3a - 3h in good to excellent yield.
