The first Pd(0)-catalyzed carbene insertion into Si-Si and Sn-Sn bonds has been realized by using N-tosylhydrazones as the carbene precursors. Geminal bis(silane) and geminal bis(stannane) derivatives were obtained in good to excellent yields under mild conditions. Migratory insertion of Pd carbene is supposed to be the key step for the reaction.
首次实现了首例 Pd(0)-催化的卡宾插入 Si-Si 和 Sn-Sn 键，使用 N-对甲苯磺酰腙作为卡宾前体。在温和条件下，以良好到优异的产率得到了偕二硅烷和偕二锡烷衍生物。Pd 卡宾的迁移插入被认为是反应的关键步骤。
