A series of 4-vinylbiphenyl derivatives were synthesized by Pd(OAc)(2)/PCy3-catalyzed Suzuki-Miyaura reaction in the presence of K3PO4.3H(2)O as base in toluene at 80 degrees C for only 10-30min, and the corresponding products achieved 65-98% yields. According to this efficient C?C bond-forming method, the obtained yields of 4-vinylbiphenyl liquid crystal compounds were up to 92-96%.
