P: The synthesis of the first stable disilyne bisphosphine adduct is reported. Its X‐ray structure, showing a short SiSi 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)
2 P或2 P:报道了第一种稳定的二甲硅烷基双膦加合物的合成。它的X射线结构显示出短的SiSi键并具有一定的多重键特征,说明与其他配体相比,膦对Si I的独特配体效应。二硅炔衍生物在室温下会与CO 2迅速反应,从而允许非金属介导的将CO 2直接还原为CO(见图)。
