Synthesis of 1,4-and 1,3-Benzenedicarbonyl Thioureas by Phase Transfer Catalysis
Abstract:
Title thioureas have been synthesized by reaction of substituted phenylamines with 1,4-or 1,3-benzenedicarbonyl chloride and ammonium thiocyanate by solid-liquid phase transfer catalysis using polyethylene glycol-400(PEG-400) as a catalyst in yield of 80%~96%. The compounds were characterized and identified by elemental analysis, IR and 1H NMR.
