Abstract

2, 2'-Bipyridine (bpy) and a series of dimethyl-2, 2'-bipyridines were synthesized from 2- bromopyridine and 2-bromomethylpyridines, respectively, using an electrochemical process catalyzed by nickel complexes. The method is simple and efficient, with isolated yields between 58 and 98% according to the structure. We first studied the influence of the presence and the position of the methyl group on the yield, using N, N-dimethylformamide ...
