Gold can do it! The activation of disilanes at gold was observed experimentally and analyzed theoretically. Upon chelation with two or even only one phosphine donor, the oxidative addition of σ-Si-Si bonds proceeds readily at low temperatures. These results show an unexpected similarity between gold and the other late transition metals towards σ bond activation. © 2011 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
