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

A radical decarboxylation/annulation of acrylamides with aliphatic acyl peroxides was developed, giving a series of linear alkylated oxindoles in moderate to good yields. The reaction used aliphatic acyl peroxides as the linear alkyl radical source and tolerated a broad scope of substrates under metal-free conditions, offering a simple and efficient approach toward alkylated oxindoles.
