Phosphane-stabilized phosphenium cations react with silanes to effect either reduction to primary or secondary phosphanes, or formation of P-P bonded species depending upon counteranion. This operates for in situ generated phosphenium cations, allowing catalytic reduction of P(III)-Cl bonds in the absence of strong reducing agents. Anion and substituent dependence studies have allowed insight into the competing mechanisms involved.
膦稳定的磷翁阳离子与硅烷反应，根据抗衡阴离子的不同，可实现磷翁阳离子的还原为一级或二级膦，或者形成 P-P 键合物种。这对于原位生成的磷翁阳离子也适用，允许在没有强还原剂的情况下催化还原 P(III)-Cl 键。阴离子和取代基依赖性研究使人们能够深入了解涉及的竞争机制。
