摘要：

The lithiation of different diaryl ketones 1 with an excess of lithium powder and a catalytic amount (8 mol %) of naphthalene in tetrahydrofuran at -30-degrees-C leads to the formation of the corresponding dianions of the type I, with Met=Li, which react with several electrophiles (E+=MeI, EtBr, PriCHO, PhCHO, cyclohexanone, MeCN) to give, after hydrolysis, the expected substituted diarylmethanols 2.
