A β-Diketiminate-Supported Boron Dication

Abstract

The first example of a mononuclear boron dication has been prepared and isolated as the bis(trifluoromethanesulfonate) salt of its 2,2‘-bipyridine complex. The compound [(HC(CMe)2(NC6F5)2(bipy)B][OTf]2 (1) was prepared by treatment of the β-diketiminate-supported boron bis(trifluoromethylsulfonate) [(HC(CMe)2(NC6F5)2B(OTf)2] (2) with 2,2‘-bipyridine. The X-ray crystal structures of 1 and 2 were determined, and DFT calculations were performed on 1 and [(HC(CMe)2(NC6F5)2B]2+.
