An efficient and facile method was developed for the synthesis of C3‐cyanoalkylated quinoxalin‐2 (1H)‐ones via a C–H/C–H cross dehydrogenation coupling between quinoxalin‐2 (1H)‐ones and aliphatic nitriles. The method enables the β‐or γ‐site‐selective C− H activation of aliphatic nitriles, giving the corresponding products in moderated to good yields. The reaction demonstrated a broad substrate scope and useful synthetic application ability.
