Procedure

To a solution of benzhydrol (184 mg, 1 mmol) in methylene chloride (1 mL) is added 0.2 g 90 weight percent HF/10 weight percent acrylic acid polymer, 100,000 m. wt., and the solution stirred until complete by TLC. The liquid is decanted and the gel washed with 2×1 mL methylene chloride. The organic layers are combined and washed with 1 mL water, 1 mL NaHCO3, dried through MgSO4 and evaporated. Diphenylmethane is afforded.
