A new family of cationic, bidentate gold(III) fluoride complexes have been prepared and characterized, showing reactivity with cyano and acetylene nucleophiles. The resulting arylgold(III)C(sp) complexes exhibit higher rates of C(sp(2))-C(sp) bond formation compared to phosphine-based monodentate systems.
A new family of cationic, bidentate (P<<^>>N)gold(III) fluoride complexes has been prepared and a detailed characterization of the gold-fluoride bond has been carried out. Our results correlate with the observed reactivity of the fluoro ligand, which undergoes facile exchange with both cyano and acetylene nucleophiles. The resulting (P<<^>>N)arylgold(III)C(sp) complexes have enabled the first study of reductive elimination on (P<<^>>N)gold(III) systems, which demonstrated that C(sp(2))-C(sp) bond formation occurs at higher rates than those reported for analogous phosphine-based monodentate systems.
