The diphosphine-disilane iPr2(o-C6H 4)SiMe2SiMe2(o-C6H 4)PiPr2 reacts with AuCl(SMe2) via coordination of the two phosphines and oxidative addition of the σ-Si-Si bond. The ensuing bis(silyl) gold(III) complex has been unequivocally authenticated by NMR spectroscopy at -60 °C. Upon heating, it evolves cleanly to give a disiloxane gold(I) complex that has been fully characterized, including by X-ray diffraction analysis. Oxidation of the disilane proceeds via an original Au(I)/Au(III) redox sequence. According to 18O labeling experiments, both water and dioxygen are competent oxygen sources. Oxidative addition of the σ-Si-Si bond to form a bis(silyl) gold(III) complex seems to be a prerequisite for the disilane → disiloxane conversion to occur.
