The first silyl-substituted silyliumylidene ions are reported. The scope of a previously described convenient one-step procedure for the preparation of N-heterocyclic carbene (NHC) stabilized silyliumylidene ions via dehydrochlorination from a Si(iv) precursor with NHCs is expanded to silyl-based substituents as well as aryl substituents with reduced steric bulk.
报道了首例硅基取代的亚硅烯离子。一种先前描述的便捷一步法，通过用氮杂环卡宾（NHC）从硅（IV）前体进行脱氯化氢反应制备NHC稳定的亚硅烯离子，该方法的适用范围扩大到了硅基取代基以及空间位阻较小的芳基取代基。
