The base-stabilized silacyclopropylidene 1 behaves as a versatile strongly nucleophilic ligand toward transition metals. The strong silylene-metal binding related to both increased σ-donating and π-accepting character of silylene 1 compared to N-heterocyclic carbenes (NHCs) allowed the synthesis of robust and air-stable silylene complexes. Of particular interest, the corresponding platinum(0) complex 6 exhibits high stability and a high level of selectivity and catalytic activity in hydrosilylation reactions that is superior to that of the related NHC-Pt(0) complexes.
碱稳定的硅环丙叉 1 作为一种对过渡金属具有多种用途的强亲核配体。与 N - 杂环卡宾(NHCs)相比,硅烯 1 的 σ 供电子和 π 吸电子特性增强,这使得其与金属形成的强硅烯 - 金属键得以实现,从而能够合成出稳定且对空气稳定的硅烯配合物。特别值得关注的是,相应的铂(0)配合物 6 在硅氢化反应中表现出高稳定性、高选择性和催化活性,优于相关的 NHC - Pt(0)配合物。
