Tributylvinyltin → HCID 117607167, compound

Participants

Reaction Steps

A mixture of 2,2′,5′-trichloro-5-iodo-4-methoxy-1,1′-biphenyl (1.17 g, 2.9 mmol), tributyl(vinyl)stannane (1.1 g, 3.5 mmol), Pd(PPh3)4 (670 mg, 0.6 mmol) in toluene (30 mL) was stirred at reflux under argon for 6 h. The reaction mixture was quenched with KF aqueous solution and then extracted with ethyl acetate. The organic layer was washed with brine, dried over Na2SO4 and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (petroleum ether/DCM=100:1) to afford the desired product (310 mg, 35% yield) as a white solid.
