The efficient heterogeneous catalyst containing copper (II) bis-benzothiazole complex supported on functionalized magnetic nanoparticles used for epoxidation of alkenes with tert-BuOOH

Oxidation of alcohols to carbonyl compounds over graphene oxide functionalized with copper-thiazole as a catalyst

“…The GO-CPTMS (500 mg) was dispersed in 60 ml of DMF with stirring for 30 min. Then, the prepared 3,5 -bis(2 -benzothiazolyl)pyridine (BTP ligand) (80 mg) (Scheme 2) [49] was added to the resulting sample and re uxed for 24 h. Then, the resulting solid was ltrated and washed carefully with DMF and Et 2 O. Finally, the GO-CP-BTP (200 mg) was dispersed in methanol (20 mL) and CuBr 2 salt (100 mg) was added to this solution.…”
