Covalently Anchored Molecular Catalyst onto a Graphitic Carbon Nitride Surface for Photocatalytic Epoxidation of Olefins.

ABSTRACT: This study explores an innovative photocatalytic approach using pristine graphitic carbon nitride (C₃N₄) to anchor iron salen-type complexes (FeSalenCl₂) without the need for additional linkers or heterojunctions. The resulting hybrid catalyst, [C₃N₄-FeCl(Salen)]_Chem, exhibits a promising catalytic performance in the selective epoxidation of cyclic and linear olefins using gaseous oxygen as the oxidant. The catalyst's selectivity closely resembles that of the free iron complex, and its effectiveness varies depending on the olefin substrate. Additionally, solvent selection plays a critical role in achieving optimal performance, with acetonitrile proving to be the best choice. The study demonstrates the potential of C₃
