2-Carbomethoxy-3-hydroxyquinoxaline-di-N-oxide was identified as an efficient novel ligand for the copper-catalyzedcouplingreactions of aryl iodides, bromides, and chlorides with aliphatic amines and N-containing heterocycles under mild conditions. The catalytic system showed great functional-group tolerance and excellent chemoselectivity.

available ruthenium pincer complex (Ru‐MACHO‐BH) as a catalyst, the challenging direct hydrogenation of lactams and analogues has been successfully accomplished to deliver corresponding value‐added aminoalcohols in good‐to‐excellent yields under mild reaction conditions. Remarkably, in addition to N‐protected lactams, unprotected ones could also be readily reduced in the presence of a catalytic amount
