Abstract: | A series of 4‐vinylbiphenyl derivatives were synthesized by Pd(OAc)2/PCy3‐catalyzed Suzuki–Miyaura reaction in the presence of K3PO4.3H2O as base in toluene at 80°C for only 10–30 min, 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%. Copyright © 2013 John Wiley & Sons, Ltd. |
