▎ 摘　　要

In this study, magnetic graphene oxide was functionalized with N-amidinoglycine as efficient bioligand for the copper ions immobilization. This nanocomposite was characterized using Raman, XRD, FE-SEM, EDX, ICP-OES, VSM and FT-IR analysis. This nanocomposite was showed high catalytic activity in the synthesis of alkyl aminophenols via one-pot Petasis Boron Mannich reaction and simply recovered from the reaction mixture by using an external magnetic field and reused for five catalytic cycle without any pre-activation with acceptable yields.
