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.

Cu II固定在A基甘氨酸官能化的氧化石墨烯上促进烷基氨基酚的合成

在这项研究中，氧化石墨烯被N- ami氨基甘氨酸官能化，作为固定铜离子的有效生物配体。使用拉曼，XRD，FE-SEM，EDX，ICP-OES，VSM和FT-IR分析对这种纳米复合材料进行了表征。该纳米复合材料通过一锅Petasis Boron Mannich反应在烷基氨基苯酚的合成中显示出高催化活性，并通过使用外部磁场从反应混合物中简单地回收，并在没有任何预活化的情况下重新用于五个催化循环，且收率令人满意。
