The vinylation of 4-bromo-4'-hydroxybiphenyl and ethyl acrylate was st
udied using the catalyst NiCl2.H2O/PPh3 in the presence of inorganic b
ase. Ethyl 4-(4'-hydroxyphenyl)cinnamate was formed as vinylation prod
uct with a selectivity as high as 98%. The effect of solvent, ligand a
nd base for some halides was examined to show the applicability of the
catalyst system.
