A mild, aerobic, catalytic synthesis of nitriles directly from alcohols and aqueous ammonia proceeds via a dehydrogenation cascade mediated by catalytic CuI, bpy, and TEMPO in the presence of oxygen. The substrate scope includes various functionalized aromatic and aliphatic alcohols. This protocol also enabled a one-pot synthesis of various biaryl heterocycles directly from commercially available alcohols.
