A scalable cyanation of gem-difluoroalkenes to (hetero)arylacetonitrile derivatives was developed. This strategy features mild reaction conditions, excellent yields, wide substrate scope, and broad functional group tolerance. Significantly, in this reaction, aqueous ammonia offers a “N” source for the “CN” reagent and entirely avoids the use of toxic cyanating reagents or metal catalysis. Hence, we
开发了一种可扩展的偕二氟烯烃氰化为(杂)芳基乙腈衍生物的方法。该策略具有反应条件温和、产率高、底物范围广、官能团耐受性广等特点。值得注意的是,在该反应中,氨水为“CN”试剂提供了“N”源,并且完全避免使用有毒的氰化试剂或金属催化剂。因此,我们为芳基乙腈的合成提供了一种绿色替代方法。
