A Cu/ABNO-catalyzed aerobic oxidative coupling of diols and a broad range of primary amines provides N-substituted pyrroles. The reaction proceeds at room temperature with an O2 balloon as the oxidant using commercially available materials as the substrates and catalysts. The catalyst system offers a good tolerance to sensitive functional groups.
