The　Minisci　alkylation　of　N-heteroarenes　with　unactivated　alkanes　under　external　oxidant-free　conditions　provides　an　economically　attractive　route　to　access　alkylated　N-heteroarenes　but　remains　underdeveloped.　Herein,　a　new　electrophotocatalytic　strategy　to　access　alkyl　radicals　from　strong　C(sp(3))-H　bonds　was　reported　for　the　following　Minisci　alkylation　reactions　in　the　absence　of　chemical　oxidants.　This　strategy　realized　the　first　example　of　cerium-catalyzed　Minisci　alkylation　reaction　directly　from　abundant　unactivated　alkanes　with　excellent　atom　economy.　It　is　anticipated　that　the　general　design　principle　would　enrich　catalytic　strategies　to　explore　the　functionalizations　of　strong　C(sp(3))-H　bonds　under　external　oxidant-free　conditions　with　H-2　evolution.
