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 )-C(sp) bond formation occurs at higher rates than those reported for analogous phosphine-based monodentate systems.
已制备出一类新型的阳离子双齿（P^N）金（III）氟化物配合物，并对金-氟键进行了详细表征。我们的结果与所观察到的氟配体的反应活性相关，该配体可与氰基和乙炔亲核试剂轻松发生交换。由此得到的（P^N）芳基金（III）C（sp）配合物使得首次对（P^N）金（III）体系上的还原消除反应进行研究成为可能，研究表明C（sp）-C（sp）键的形成速率高于类似的基于膦的单齿体系所报道的速率。
