1-benzyloxy-4-ethynyl-benzene (70 g, 0.3365 mol), Bu3SnH (59 mL, 0.3365 mol) and Ph(PP3)2Cl2 (120 mg, 0.1718 mmol) were stirred in THF (500 mL) at 25° C. for 16 h and then refluxed for 1 h. The resulting solution was concentrated and then purified on SiO2 (2% ˜5% ethyl acetate/hexane) to yield tributyl-[1-(4-benzyloxy-phenyl)-vinyl]-stannane.
