| Abstract: | Hetero biaryls were prepared with high yields from heteroaryl halides by Pd/C-catalyzed reductive coupling reaction in a H2O-alcohol system. This method has advantages of environmental benignity, simplicity, the potential for recycling of catalyst, good yield and not using phase-transfer agent. The effects of various alcohols, bases and substrates on the reaction were discussed. |
