A graphene based hybrid with copper nanoparticles (Cu-Cu2O/GO-NH2) as a heterogeneous catalyst for the preparation of β-ketophosphonates was investigated. Compared with traditional homogeneous catalysis, Cu-Cu2O/GO-NH2 catalyst can be recovered from the reaction system. The present methodology provides a facile and efficient approach to access a wide range of β-ketophosphonates in good yields. This reaction can be conducted under base-free conditions without any external co-catalysts, which provides an alternative strategy for the synthesis of β-ketophosphonates.

Key words: Cu nanoparticles, graphene, oxyphosphorylation, heterogeneous catalysis, β-ketophosphonates
