Ullmann-type cross-coupling reactions have been performed by a heterogeneous mesoporous copper manganese oxide (meso Cu/MnOx) material. The catalytic protocol is ligand free with broad substrate scope and showed excellent catalyst reusability. Experimental and density functional theory (DFT) analysis suggested an oxidative addition of the phenol derivatives at the Cu center with a charge delocalization over the oxide surface.
