We report a vinyl cyanation reaction of vinyl triflates and readily available 1,4-dicyanobenzene through a nickel-catalyzed reductive coupling process. The reaction is operated under mild conditions with remarkable functional-group compatibility. Cyclic vinyl triflates with various ring sizes and substituents at different positions all reacted smoothly. The synthetic utility is demonstrated by the
我们报告了乙烯基三氟甲磺酸酯和容易获得的 1,4-二氰基苯通过镍催化还原偶联过程的乙烯基氰化反应。该反应条件温和,官能团相容性好。不同环尺寸和不同位置取代基的环状乙烯基三氟甲磺酸酯均能顺利反应。合成效用通过药物和天然化合物的衍生化、放大合成和各种官能团转化来证明。初步机理研究表明,三氟甲磺酸乙烯酯对镍催化剂的氧化加成反应比 1,4-二氰基苯更具反应性。
