実験手順
A mixture of 1.2 benzenedimethanol (1.41 g, 10 mmol), carbontetrabromide (3.648 g, 11 mmol), triphenylphosphine (2.885 g, 11 mmol) in dry methylene chloride (50 ml) was stirred at rt over 2 days under argon. The solvent was removed under reduced pressure and the residue chromotographed (flash silica gel, 1:1 t-butyl methyl ether: hexanes) to afford the title compound as a white solid. (0.99 g, 49%)
