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.… Click to show full 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.
