also the fine‐tuning of physicochemical and biological properties of drugs, agrochemicals and polymers. We report here a general and practical photochemical strategy enabling the site‐selective chlorination of sp3 C−H bonds. This process exploits the ability of protonated N‐chloroamines to serve as aminium radical precursors and also radical chlorinatingagents. Upon photochemical initiation, an efficient
The photoredox activation of inert chloroalkanes for the cross-coupling reaction with olefins, with a broad functional group tolerance under mild conditions is presented. By combining UV/Vis spectroscopy, EPR, radical clock and deuterium-labelling experiments, [Ni(Py2Tstacn)]+ is proposed to be catalytically competent to activate the Csp3−Cl bond, forming a free radical, which reacts with the alkene
