1 mmole (182 mg) of benzophenone dissolved in 5 mL THF was stirred with 0.5 g of 12% Li-AG and solid state proton sources such as NH4Cl, (NH4)2HPO4, or dropwise addition of glacial AcOH at room temperature after a deep blue colored solution is produced. The color of the reaction vessel gradually fades and becomes grey at the end indicating complete consumption of lithium. The reaction mixture was filtered, the solids washed with hexane, and the solvent was removed from the combined organic solutions under vacuum to obtain a white solid corresponding to diphenyl methanol as confirmed by 1H, 13C NMR and ESI-MS. See FIGS. 3A-3C.
