A series of 4-vinylbiphenyl derivatives were synthesized by Pd(II)-1,2-diaminocyclohexane complex catalyzed Suzuki-Miyaura reactions in the presence of K3PO4?3H2O as base in toluene at 80 ° C and the corresponding products achieved 39-95% yields. According to this efficient C-C bond-forming method, the obtained yields of 4-vinylbiphenyl liquid crystal compounds were up to 89%.

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
Synthesis of 4-substituted styrene compounds via palladium-catalyzed suzuki coupling reaction using free phosphine ligand in air

experimental part, p. 196 - 205 (2010/03/30)
The air-stable and easy to prepare nonsymmetric Schiff base ligands have been synthesized and proven to be efficient ligands for Suzuki cross-coupling reaction between aryl bromides and arylboronic acids using PdCl 2(CH3CN)2 as palladium source under aerobic conditions. The coupling reaction proceeded smoothly using N-[(3,4- dimethoxyphenyl)methylene]-1,2-benzenediamine (L3) as ligand under mild conditions to provide 4-substituted styrene compounds in good yields.
