The carbene chemistry of light group 15 elements such as phosphorus has resulted in hundreds of fascinating compounds and is providing new avenues of research in main-group chemistry, transition metal chemistry, and catalysis. In contrast, the analogous chemistry of bismuth (metal) continues to present major challenges and as a result there are only a few reports on carbene−bismuth chemistry. Our laboratory recently reported a series of N-Heterocyclic carbene- (NHC) and cyclic(alkyl)(amino)carbene (CAAC)-bismuth complexes. While CAAC complexes of bismuth(III) chloride (BiCl3) are extremely reactive and have not been isolated, CAAC does coordinate to phenylbismuth dichloride [Bi(Ph)Cl2], allowing us to synthesize CAAC-Bi(Ph)Cl2 adducts. These molecules represent the first structurally characterized examples of CAAC-coordination to bismuth. This presentation will highlight our group’s work regarding the reactivity of these molecules.
