Horner–Wadsworth–Emmons/hydrogenation tandem reaction was achieved using ammonia as electron and proton donors. The reaction could give two-carbon-elongated ester and nitrile from aldehyde or ketones directly. This reaction could proceed with a catalytic amount of base or even without a base. The ammonia provides both the electron and proton for this tandem reaction and enables the catalyst-free hydrogenation
使用氨作为电子和质子供体实现了电化学 Horner-Wadsworth-Emmons/氢化串联反应。该反应可以直接由醛或酮得到双碳延伸的酯和腈。该反应可以在催化量的碱或什至没有碱的情况下进行。氨为该串联反应提供电子和质子,并使 α,β-不饱和 HWE 中间体的无催化剂氢化成为可能。报告了 40 多个例子,并且可以容忍包括杂环和羟基在内的官能团。
