Thionyl Chloride → HCID 18955940, compound

Participants

Reaction Steps

The crude benzhydryl alcohol from above (31.8 g, 107 mmole) was dissolved in 150 ml of dichloromethane and 11.7 ml (1.5 equiv.) of thionyl chloride was added dropwise over ten minutes. The solution was stirred overnight at room temperature and the solvent was removed under vacuum. The crude product was redissolved in 100 ml of toluene and the solvent was again removed under vacuum in order to eliminate excess thionyl chloride, providing crude product as a dark oil. The material was purified by short path distillation (Kugelrohr apparatus, 150° C., 0.5 mm) to give 25.8 g (76%) of (2-bromophenyl)chloro(4-chlorophenyl)methane as a pale yellow oil.
