Manganese salophen covalently anchored to amino-functionalized graphene oxide as an efficient heterogeneous catalyst for selective epoxidation.

ABSTRACT: Epoxidation of olefins catalyzed by manganese(iii) salophen (MnSalop) immobilized on graphene oxide (GO) modified with 3-aminopropyltrimethoxysilane (GO·NH₂) has been reported. Characterization of the solid catalyst by FTIR, DR UV-Vis, FESEM, XRD, elemental scanning mappings, TGA/DTG, BET measurements, and ICP analysis aided in understanding the catalyst morphology. It confirmed that there was no significant demetallation or chemical change in MnSalop-GO·NH₂. The heterogeneous catalyst (MnSalop-GO·NH₂) showed high efficiency in the oxidation of different olefins with H₂O₂ as a green oxygen donor agent assisted by NaHCO₃ as co-catalyst at room temperature. The alkenes were oxidized to their corresponding epoxides with 88-100%
