Synthesis and isolation of dinuclear N,C-chelate organoboron compounds bridged by neutral, anionic, and dianionic 4,4′-bipyridineviareductive coupling of pyridines

Abstract

The reaction of Bppy(Mes)2 (BN1; ppy = 2-phenylpyridine) and BCH2ppy(Mes)2 (BN3) with the reducing reagent KC8 resulted in the C-C bond formation via intermolecular radical coupling to generate the 4,4’-bipyridyl...
