Abstract The transient electron donor–acceptor (EDA) complex has been an emerging area in the photoinduced organic synthesis field, generating radicals without exogenous transition‐metal or dye‐based photoredox catalysts. catalytic platform to form suitable photoactive EDA complexes for photochemical reduction reactions remains underdeveloped. Herein, a general reductive alkylation via strategy is described. A simple yet multifunctional system, triphenylphosphine and iodide salt, promotes decarboxylative hydroalkylation, defluorinative of trifluoromethyl alkenes, access alkanes gem ‐difluoroalkenes. Moreover, hydroalkylation can be applied more kinds electron‐deficient alkenes as Giese addition reaction.
