Abstract

The one-electron oxidizing agent [NO]PF 6 was reacted with Bu 4N[Au(C 6X 5) 2] (X = F, Cl) complexes in CH 3CN. The gold(III) complexes [Au(C 6F 5) 3(CH 3CN)] and cis-[Au(C 6Cl 5) 2(CH 3CN) 2]PF 6 were synthesized by the oxidation of gold(I) to gold(III) with the concomitant ligand rearrangement "oxidative rearrangement". The supramolecular crystal packing in the perfluorinated aryl gold(III) complex is dictated by the notably short C(sp 2)-F•••H(CH 3CN) bond distance. The [Au(C 6Cl 5) 2(CH 3CN) 2]PF 6 complex exhibits antisymbiosis, displaying equal ligands in the cis position. The electrochemical oxidation of Bu 4N[Au(C 6X 5) 2] (X = F, Cl) complexes in CH 3CN showed two irreversible peaks at 0.71 and 1.21 V (X = F) and at 0.65 and 0.91 V (X = Cl) vs Ag/AgCl. © 2012 American Chemical Society.
