摘要：

At room temperature, reacting cis-[Au(Ar)(Ar')Cl] with [PhCH2PPh3]Cl (1:1), with PPh3 plus NaClO4.H2O (1:2:1), or with PPh3 (1:1) leads to a reductive elimination giving gold(I) complexes [PhCH2PPh3][AuCl2], [Au(PPh3)2]ClO4, or [AuCl(PPh3)], respectively, and in high yields, the corresponding biaryls Ar-Ar' [Ar = C6H4N = NPh-2, Ar' = Ar (1), C6H4NO2-2 (2), C6F5 (3); Ar = Ar' = C6H3(N = NC6H4Me-4')-2, Me-5 (4); Ar = C6H4CH2NMe2-2, Ar' = Ph (5), C6H4N = NPh-2 (6), C6H3(N=NC6H4Me-4')-2, Me-5 (7)].
