A facile, efficient and environmentally-friendly protocol for the synthesis of xanthenes by graphene oxide based nanocomposite (GO-CuFe 2 O 4 ) has been developed by one-pot condensation route. The nanocomposite was designed by decorating copper ferrite nanoparticles on graphene oxide (GO) surface via a solution combustion route without the use of template. The as-synthesized GO-CuFe 2 O 4  composite was comprehensively characterized by XRD, FTIR, Raman, SEM, EDX, HRTEM with EDS mapping, XPS, N 2  adsorption-desorption and ICP-OES techniques. This nanocomposite was then used in an operationally simple, cost effective, efficient and environmentally benign synthesis of 14H-dibenzo xanthene under solvent free condition. The present approach offers several advantages such as short reaction times, high yields, easy purification, a cleaner reaction, ease of recovery and reusability of the catalyst by a magnetic field. Based upon various controlled reaction results, a possible mechanism for xanthene synthesis over GO-CuFe 2 O 4  catalyst was proposed. The superior catalytic activity of the GO-CuFe 2 O 4  nanocomposite can be attributed to the synergistic interaction between GO and CuFe 2 O 4  nanoparticles, high surface area and presence of small sized CuFe 2 O 4  NPs. This versatile GO-CuFe 2 O 4  nanocomposite synthesized via combustion method holds great promise for applications in wide range of industrially important catalytic reactions.
