Phase transfer catalyzed synthesis of arene-bis-aroyl thiourea derivatives

摘要

Reaction of arene dimines with aroyl chloride and ammonium thiocyanate under the condition of solid-liquid phase transfer catalysis using polyethylene-glycol-600 (PEG-600) as the catalyst furnishes arene-bis-aroyl thioureas 3a-l in good to excellent yield. The products have been characterized by analytical and spectral (IR and ~1H NMR) data.
