Synthesis of Cyclometalated Gold(III) Complexes via Catalytic Rhodium to Gold(III) Transmetalation


Martín, Jaime; Gómez‐Bengoa, Enrique; Genoux, Alexandre; Nevado, Cristina (2022). Synthesis of Cyclometalated Gold(III) Complexes via Catalytic Rhodium to Gold(III) Transmetalation. Angewandte Chemie Internationale Edition, 61(20):e202116755.

Abstract

A catalytic method to synthesize a broad array of cyclometalated (C^N)gold(III) complexes is reported here. An unprecedented Rh-to-AuIII transmetalation allows the facile transfer of (C^N) ligands between these two metals in a redox-neutral process. The reaction employs commercially available precursors and proceeds under mild and environmentally benign conditions. Both experimental and computational studies support a multistep transmetalation from rhodium to gold as the underlying mechanism for these transformations. This process involves first, a rate-determining transfer of the C ligand followed by the subsequent incorporation of the N donor to form the monocyclometalated (C^N)gold(III) species.
