Metal-free regio- and chemoselective hydroboration of pyridines catalyzed by 1, 3, 2-diazaphosphenium triflate
N-Heterocyclic phosphenium triflates (NHP-OTf) 1 serve as efficient catalysts for the regio- and chemoselective hydroboration of pyridines under ambient condition with good functional group tolerance. Mechanistic studies indicate that a boronium salt, [(Py)2·Bpin]OTf 4, is generated concomitant with...
