In the present study, Cu(II) immobilized on hyperbranched polyglycerol functionalized graphene oxide catalyst was prepared as a novel, green, highly efficient, and reusable heterogeneous catalyst. Then, the synthesis of naphthoquinone derivatives was performed using Go-HPG-IA-Cu(II) as a catalyst under ultrasound irradiation to afford the desired products in high yields and short reaction times. This catalyst was easily recovered and reused several times without significant loss of catalytic activity.
