Abstract

Metallic nickel, prepared by the reduction of nickel halides with lithium in glyme using naphthalene as an electron carrier, waa found to be a useful reagent for the homocoupling of benzylic mono-and polyhalides. Benzyl halides reacted with metallic nickel at room temperature to give the corresponding 1, a-diarylethanes in good to high yields and functional groups on the aromatic ring such as methoxy, chloro, bromo, nitro, cyano, and ...
