Combining ligand-enhanced backdonation and steric shielding to stabilize a mono-substituted Au( i ) carbene

Abstract

A mono-substituted Au(i) carbene was prepared by reacting HC(N2)(Dmp) (Dmp = 2,6-dimesitylphenyl) with an (o-carboranyl)-diphosphine AuNTf2 complex. It is stable up to −10 °C and was characterized by NMR spectrocopy. According to DFT calculations, the chelating P^P ligand enhances Au → Ccarb backdonation, while the Dmp substituent provides kinetic stabilization but does not bias the electronic structure of the carbene complex
