and efficient route for the synthesis of alkynylphosphonates and ynamides by aerobic oxidative alkynylation of H-phosphonates and amides with both aliphatic and aromatic alkynes using our synthesized recyclable heterogeneous Cu–MnO catalyst has been developed. The phosphorylation was carried out under base- and ligand-free conditions, and in the presence of air as the sole oxidant. The reaction is compatible
