Despite allene derivatives have been always regarded as a radical accepter in traditional radical chem. for decades, the reactivity of allene derivatives under excited state in radical chem. was rarely explored. Herein, we report an example to engage triplet-excited state of allene moiety as hydrogen-atom-transfer (HAT) partner in the activation of remote sp3 C-H bond via visible-light irradiation under mild reaction conditions with broad substrate scope and good functional-group tolerance. The reaction mechanism involving the generation of triplet excited state of allene derivative and the subsequent HAT process was supported by deuterium labeling, kinetic anal. experiments and DFT calculations
《Activation of C-H bond by visible light photosensitized allene moiety》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound([Ir(dtbbpy)(ppy)2]PF6)Category: copper-catalyst.
