N-Heterocyclic carbenes (NHCs) with a variety of oxidants promote the Mitsunobu-type coupling reactions of alcohols with phenols, carboxylic acids, and phthalimide. Experiments using a chiral alcohol indicate that these reactions proceed via SN1 or SN2 pathways depending on the polarity of the used solvents. The NHCs are consumed as reducing reagents to form their oxides as readily separable byproducts
具有各种氧化剂的N-杂环卡宾(NHC)可以促进醇与酚,羧酸和邻苯二甲酰亚胺的Mitsunobu型偶联反应。使用手性醇的实验表明,取决于所用溶剂的极性,这些反应通过SN1或SN2途径进行。NHC作为还原剂被消耗掉,形成易于分离的副产物的氧化物。
