    • When the solvent, THF-HMPA (4/1), was changed to THF-1,3-dimethyl-2-imidazolidinone (4/1), THF-1,1,3,3-tetramethylurea (4/1), or THF only, the yield of 2 decreased to 13%, 27%, or 25% yields, respectively.

    • for example, the reaction of 1a with benzophenone in the presence of Sm metal (1 equiv) gave diphenylmethyl tolyl ketone and diphenylhydroxymethyl tolyl ketone in 73% and 20% yields, respectively. 2-Adamantyl phenyl ketone was prepared in 30% yield from 1b and 2-adamantanone; However, the reaction with ketones having α-hydrogens such as cyclohexanone gave a complex mixture.
