Abstract

Well-defined cationic bismuth complexes, [Bi(NR₂)L_n]⁺, based on simple, monodentate, monoanionic amide ligands have recently been reported (R = Me, iPr, etc.). The unusual reactivity patterns of these species are highlighted, with a focus on a recently reported double CH activation reaction. Mechanistic aspects and the impact of charge on reactivity are discussed. These results are compared with literature-known strategies in bismuth-mediated CH activations, and their potential implications for future research in the field are outlined.

25 The reaction shown in Scheme 4 is also suggested to proceed as a classical deprotonation reaction (cf. ref. 24).
26 Radical mechanisms have been suggested in a few cases, but these mechanisms have not been studied in detail (e.g., ref. 7).
