One pot highly uniform Cu(0)-Cu(I) oxide nanoparticles (5–10 nm) have been synthesized on nitrogen rich mesoporous carbon nanospheres (Cu-NCN) and efficiently utilized as a heterogeneous catalyst towards hydroamination of aromatic terminal alkynes with aniline derivatives. The catalyst bed provides Cu₂O nanoparticles stabilized by nitrogen functionalities in the carbon nanospheres, which triggers the catalytic system with significantly large Turn over number (TON) and >99% selectivity towards Markovnikov addition product. The structure and morphology of the copper nanoparticles engraved carbon spheres have been studied by performing nitrogen physisorption studies (BET), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) characterization techniques.
