A triazolium salt derived N-heterocyclic carbene catalyzes the redox esterification reaction between α–β-unsaturated aldehydes and oximes. The resulting saturated oxime esters were obtained in very good yields for a broad range of aliphatic, aromatic and heteroaromatic substrates.
由三唑盐衍生的N-杂环卡宾催化α-β-不饱和醛与
肟之间的氧化酯化反应。对于广泛的脂肪族、芳香族和杂芳香族底物,最终生成饱和的
肟酯,产率非常高。
