Sodium hydride (NaH) is widely used as a Brønsted base in chemical synthesis and reacts with various Brønsted acids, whereas it rarely behaves as a reducing reagent through delivery of the hydride to polar π electrophiles. This study presents a series of reduction reactions of nitriles, amides, and imines as enabled by NaH in the presence of LiI or NaI. This remarkably simple protocol endows NaH with
氢化钠(NaH)在化学合成中被广泛用作布朗斯台德碱,并与各种布朗斯台德酸发生反应,而它几乎不通过将氢化物传递给极性π亲电试剂来充当还原剂。这项研究提出了在LiI或NaI存在下,NaH使腈,酰胺和亚胺发生的一系列还原反应。这种非常简单的方案使NaH具有前所未有的独特的氢化物-给体化学反应性。
