A photocatalytic site-selective functionalization of sulfamate esters derivatives was described. This transformation was achieved through amidyl radical directed 1,6-hydrogen atom transfer and intermolecular radical addition, providing a simple and practical approach for the synthesis of gem-difluoroalkene-containing sulfamate esters. Besides, this protocol proceeds under redox-neutral conditions.
