Reaktionsschritte

To a solution of 15.14 g (59.3 mmol) of bis(4-chlorophenyl)methanol in 100 mL of methylene chloride was added slowly a solution of 71.2 mL of BBr3 (71.2 mmol, 1M in CH2Cl2). The solution was stirred for at 0° C. for 1 h. Then 60 mL of water was added to quench the reaction and the reaction mixture was poured into 200 mL of methylene chloride. The water layer was extracted with methylene chloride (60 mL×2) and the combined organic layer was dried over Na2SO4 and concentrated to give the title compound; 1NMR (CDCl3) δ 6.24 (s, 1H), 7.36 (d, 4H, J=8.7 Hz), 7.41 (d, 2H, J=8.7 Hz).
