A nickel‐catalyzed alkylarylation of active alkenes with tertiary benzylamines was achieved by charge‐transfer‐complex promoted C−N bond activation. The reaction proceeded through initial Ni‐catalyzed C−N bond activation, followed by sequential radical addition, redox and proton abstraction with cleaved amine moiety in the absence of oxidant, and provides an efficient method to prepare various alkyl‐substituted

DTBP (di-tert-butyl peroxide) is utilized to mediate oxidative 1,2-difunctionalization of activated alkenes with an aryl C(sp(2))-H bond and a benzylicC(sp(3))-H bond for the synthesis of functionalized oxindoles. This reaction is a new organomediated strategy for alkene difunctionalization facilitated by Lewis acids.
