这篇文章涵盖了历史和最近的努力，催化胺和硅烷的脱氢偶联，直接形成Si-N键的方法，提供氢作为副产物。在某些应用中，这种转化可以用作传统氨基硅烷合成的可持续替代品，传统氨基硅烷合成需要腐蚀性氯硅烷，同时为形成的每个Si-N键产生一当量的铵盐废物。这些优点推动了跨越周期表的Si-N脱氢偶联催化剂的发展，提供了导致效率和选择性进步的机理见解。考虑到所使用的前体的差异，依赖的表征方法，以及有针对性的应用，本文强调了单体氨基硅烷的形成，分别从低聚物和聚合物氨基硅烷。最近的一项研究，允许锰催化合成全氢聚硅氮烷和商业化学气相沉积前体的特点，并讨论了推进硅-氮脱氢偶联催化领域的关键机会。
This article covers historical and recent efforts to catalyse the dehydrocoupling of amines and silanes, a direct method for Si–N bond formation that offers hydrogen as a byproduct. In some applications, this transformation can be used as a sustainable replacement for traditional aminosilane synthesis, which demands corrosive chlorosilanes while generating one equivalent of ammonium salt waste for each Si–N bond that is formed. These advantages have driven the development of Si–N dehydrocoupling catalysts that span the periodic table, affording mechanistic insight that has led to advances in efficiency and selectivity. Given the divergence in precursors being used, characterization methods being relied on, and applications being targeted, this article highlights the formation of monomeric aminosilanes separately from oligomeric and polymeric aminosilanes. A recent study that allowed for the manganese catalysed synthesis of perhydropolysilazane and commercial chemical vapor deposition precursors is featured, and key opportunities for advancing the field of Si–N dehydrocoupling catalysis are discussed.
