ABSTRACT 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.
