Abstract

The dimethyl bismuth cation, [BiMe2(SbF6)], has been isolated and characterized. Reaction with BiMe3 allows access to the first compound featuring Bi→Bi donor–acceptor bonding. In solution, dynamic behavior with methyl exchange via an unusual SE2 mechanism is observed, underlining the unique properties of bismuth species as soft Lewis acids with the ability to undergo reversible Bi−C bond cleavage.
