摘要
The synthesis and characterization of the first gold(III)-arene complexes are described. Well-defined (P,C)-cyclometalated gold(III)-aryl complexes were prepared and characterized by NMR spectroscopy. These complexes swiftly and cleanly reacted with norbornene and ethylene to provide cationic gold(III)-alkyl complexes, in which the remote phenyl ring was eta(2)-coordinated to gold. The interaction between the aromatic ring and the gold(III) center was thoroughly analyzed by NMR spectroscopy, X-ray diffraction, and DFT calculations. The p-arene coordination was found to significantly influence the stability and reactivity of low coordinated gold(III) alkyl species.
