supported on grapheneoxide (GO) have been synthesized for the first time from Cu2S, and used as highly efficient heterogeneous catalysts for oxidative ortho-selective C–H aminomethylation of phenols with N,N-dimethylbenzylamines. The NPs (30–80 nm) have been characterized by HRTEM, SEM-EDX, PXRD, FTIR, Raman, ICP-AES and XPS analyses. The NP catalyzed sp2–sp3 crossdehydrogenativecoupling (CDC) features
