In this paper we describe the synthesis and reactivity of the diphenylphosphine derivatives [Au(C 6 F 5 )(PPh 2 H)] and trans ‐[Au(C 6 F 5 ) 2 (PPh 2 H) 2 ]ClO 4 . Reactions of the latter or the neutral [Au(C 6 F 5 ) 3 (PPh 2 H)] with the appropriate Group 11 metal reagents (M=Au, Ag, Cu) in the presence of acetylacetonate afford a series of novel Au III ‐M phosphido‐bridged complexes, which have been scarcely represented to date. The crystal structure of the tetranuclear [{Au(C 6 F 5 ) 2 (μ‐PPh 2 ) 2 Ag} 2 ] and the dinuclear [Au(C 6 F 5 ) 3 (μ‐PPh 2 )M(PPh 3 )] (M=Au, Ag) complexes were established by X‐ray diffraction methods. The synthesis and deprotonating activity of the anionic gold( III ) complex PPN[Au(C 6 F 5 ) 3 (acac)] (PNN=[N(PPh 3 ) 2 ] + ) was studied.
