Silylenes, divalent silicon(II) compounds, once considered highly reactive and transient species, are now widely employed as stable synthons in main-group and coordination chemistry for myriad applications. The synthesis of stable silylenes represents a major breakthrough, which led to extensive exploration of silylenes in stabilizing low-valent main-group elements and as versatile ligands in coordination chemistry and catalysis. In recent years, the exploration of transition metal complexes stabilized with silylene ligands has captivated significant research attention. This is due to their robust σ-donor characteristics and capacity to stabilize transition metals in low valent states. It has also been demonstrated that the transition metal complexes of silylenes are effective catalysts for hydroboration, hydrosilylation, hydrogenation, hydrogen isotope exchange reactions, and small molecule activation chemistry. This review article focuses on the recent progress in the synthesis and catalytic application of transition metal complexes of silylenes.
硅烯，即二价硅（II）化合物，曾被认为是高活性的瞬态物种，如今在主族化学和配位化学中作为稳定的合成子被广泛用于众多应用。稳定硅烯的合成是一项重大突破，这引发了对硅烯在稳定低价主族元素方面以及作为配位化学和催化中通用配体的广泛探索。近年来，对用硅烯配体稳定的过渡金属配合物的探索引起了大量研究关注。这是因为它们具有强大的σ供体特性以及在低价态稳定过渡金属的能力。还已证明，硅烯的过渡金属配合物是硼氢化、硅氢化、氢化、氢同位素交换反应以及小分子活化化学的有效催化剂。这篇综述文章聚焦于硅烯过渡金属配合物的合成及催化应用的最新进展。
