PHASE TRANSFER CATALYZED SYNTHESIS OF THIOSEMICARBAZIDE AND bis-THIOSEMICARBAZIDE DERIVATIVES OF 2-ETHOXYBENZOIC ACID
摘要:
Reaction of aryloxyacetic acid hydrazide or arenedioxydiacetic acid hydrazide with 2-ethoxybenzoy chloride and ammonium. thiocyanate under the condition, of solid-liquid phase transfer catalysis using polyethylene glycol-400 (PEG-400) as tire catalyst,yielded the corresponding thiosemicarbazide or bisthiosemicarbazide derivatives of 2-ethoxybenzoic acid in good-to-excellent yield.
