Despite the fundamental importance of efficient and selective synthesis of widely useful alkylarenes, the direct catalytic C(sp2)–H alkylation of unactivated arenes with a readily available alkyl halide remains elusive. Here, we report the catalytic C(s
A catalytic method for the C–H alkylation of cubanes is described. Some hydrogen atom transfer catalysts enable the direct abstraction of a hydrogen atom from the C–H bond of cubanes, followed by conjugate addition of the generated cubyl radicals to electron-deficient alkenes. Synthetic applicati...
