Participants

Reaction Steps

To a stirred solution of 4-bromo-4'-chlorobiphenyl (16 g; F. R. Shaw and E. E. Turner. J. Chem. Soc., 285 (1932) ), isopropenyl acetate (9 g) and dichlorobis(tri-o-tolylphosphine)palladium (0.47 g) in dry toluene (30 ml), under nitrogen, was added tributyltin methoxide (25.9 ml; Aldrich). The mixture was stirred and heated at 100° for 5 hr, cooled and the solvent evaporated in vacuo. The residue was chromatographed on silica gel, eluting with cyclohexane then ether. The resultant solid was recrystallised from cyclohexane to afford the title compound (10 g), m.p. 79°-81°.
