p-Selective (sp2)-C-H functionalization of electron rich arenes have been achieved for acylation and alkylation reaction, respectively, with acyl/alkylselenides by organic photoredox catalysis involving interesting mechanistic pathway.

By merging C–C and C–F bond cleavage, we developed a regioselective ring opening/gem-difluoroallylation of cyclopropyl ketones with α-trifluoromethylstyrenes, which proceeds under the catalysis of iron with the combination of manganese and TMSCl as the reducing agents, providing a new entry to the synthesis of carbonyl-containing gem-difluoroalkenes. Remarkably, the ketyl radical-induced selective
