Synthesis of a Stable Disilyne Bisphosphine Adduct and Its Non‐Metal‐Mediated CO₂ Reduction to CO

Abstract

Two P or not two P: The synthesis of the first stable disilyne bisphosphine adduct is reported. Its X-ray structure, showing a short SiSi bond with a certain multiple-bond character, illustrates the peculiar ligand effect of phosphine towards SiI compared to other ligands. The disilyne derivative rapidly reacts with CO2 at room temperature, thus allowing the non-metal-mediated direct reduction of CO2 to CO (see picture).
