| Abstract: | Using PEG-400/H2O as the reaction medium and Pd(OAc)2 as the catalyst, a series of biphenyl compounds (3a~3h) were synthesized by the cross-coupling reactions of aryl halides with arylboronic acids under ligand-free conditions. The structures were characterized by 1H NMR and 13C NMR, and the yield of the cross-coupling were 30%~99%. PEG/H2O as reaction solvent can reduce environmental pollution and realize green coupling reaction. |
