4,4'-Dichlorobenzhydrol → Benzene, 1,1'-(bromomethylene)bis(4chloro-

Participants

Reaction Steps

To a solution of bis(4-chlorophenyl)methanol (2.0 g) and carbon tetrabromide (5.2 g) in tetrahydrofuran (30 ml) was added triphenylphosphine (4.2 g). The mixture was stirred at room temperature for 1 hours. After the mixture was filtered off, the solvent was removed in vacuo. The residue was dissolved in n-hexane (30 ml) and filtered off. The filtrate was evaporated and the residue was purified by distillation at reduced pressure to give bis(4-chlorophenyl)bromomethane as an oil (2.43 g).
