To a solution of 1.14 g (0.004 mol) of chloromethyl(4-phenylphenyl)divinylsilane in 10 ml of toluene is added 0.54 g (0.005 mol) of potassium imidazole and 0.05 g of tetrabutylammonium bromide. The mixture is refluxed under nitrogen for two days, cooled, diluted with ether-hexanes, and washed with water and brine. Removal of solvent gives an oil which is purified by silica gel chromatography, eluting with 9:1 dichloromethane-ether, to give the title compound.
