摘要：

Gold(III) pi-complexes have been authenticated recently with alkenes, alkynes, and arenes. The key importance of Pd-II pi-allyl complexes in organometallic chemistry (Tsuji-Trost reaction) prompted us to explore gold(III) pi-allyl complexes, which have remained elusive so far. The (P,C)Au-III(allyl) and (methallyl) complexes 3 and 3 ' were readily prepared and isolated as thermally and air-stable solids. Spectroscopic and crystallographic analyses combined with detailed DFT calculations support tight quasi-symmetric eta(3)-coordination of the allyl moiety. The pi-allyl gold(III) complexes are activated towards nucleophilic additions, as substantiated with beta-diketo enolates.
