transition metal‐free approach to achieve the selective cleavage of the α‐carbonyl C(sp3)−H bond in alkyl esters by using inexpensive, low‐toxic, and insensitive perfluoroalkyl iodide as the radical initiator has been developed. A variety of enamides, N‐heterocycles, amides, thiophenols, and phenols could be successfully incorporated into functionalized alkyl groups by intermolecular amination, thioetherification
通过使用廉价,低毒且不敏感的全氟烷基碘作为自由基引发剂,开发了一种有效的无过渡金属方法,可实现烷基酯中α-羰基C(sp 3)-H键的选择性裂解。通过分子间胺化,硫醚化和醚化,可以将各种酰胺,N-杂环,酰胺,硫酚和酚成功地掺入官能化的烷基中。该CDC反应的显着特征是其广泛的底物范围,合成简便和温和的反应条件。
