A copper-catalyzed alkylarylation of alkenes with simple alkanes was achieved, which not only provided an efficient method to prepare various alkyl-substituted oxindoles, but also represented a novel strategy for selective sp3 C–H functionalization/C–C bond formation via a free-radical cascade process. Additionally, selective activation of unactivated (sp3)C–H and (sp2)C–H bonds by one single step
铜与简单的烷烃催化的烯烃的烷基芳基化反应不仅为制备各种烷基取代的羟吲哚提供了一种有效的方法,而且还代表了一种通过a选择性sp 3 C–H官能化/ C–C键形成的新策略。自由基级联过程。此外,在该系统中,仅一步即可选择性激活未激活的(sp 3)CH键和(sp 2)CH键,这也将为提高CH键功能化的效率提供一种新的策略。
