C(sp3)-H bonds and chloroformates has been accomplished via nickel and photoredox catalysis. A diverse range of feedstock chemicals, such as (a)cyclic alkanes and toluenes, along with late-stage intermediates, undergo intermolecular C-C bond formation to afford esters under mild conditions using only 3 equiv of the C-H partner. Site selectivity is predictable according to bond strength and polarity
通过镍和光氧化还原催化,实现了未活化的 C(sp3)-H 键和氯甲酸酯之间直接交叉偶联的方法。多种原料化学品,例如 (a) 环烷烃和甲苯,以及后期中间体,仅使用 3 当量的 CH 伙伴,在温和条件下形成分子间 CC 键即可生成酯。位点选择性是根据键强度和极性趋势来预测的,这与氯自由基作为氢原子抽象物种的中间作用一致。
