Preparation and characterization of diphenylboron cation in solution

Abstract The electrophilic abstraction of chloride ion by SbCl 5 from diphenylchloroborane in CD 3 NO 2 resulted in a transient species of which 11 B NMR chemical shift appeared at 20 ppm. This was indicative of diphenylboron cation, stabilized with electron donor O-atom of two nitromethane molecules. The experimental 11 B chemical shift for the solvated diphenylboron cation is in good agreement with that calculated by GIAO-HF/6-311+G(2d,p)//B3LYP/6-31+G(d).
