15-(4-Carboxyphenyl)-10,15,20-triphenylporphyrin manganese(III) chloride grafted on magnetic polyglycidyl methacrylate as biomimetic catalyst and their catalytic activity

Manganese(III) 5-(4-carboxyphenyl)-10,15,20-triphenylporphyrin chloride (Mn(TCPP)Cl) was grafted through amide bond on magnetic polyglycidyl methacrylate (mPGMA) cross-linked by divinylbenzene (DVB). XRD, ICP-AES, N ₂ physisorption, SEM, TEM, FTIR and thermal analysis were employed to analyze these novel materials. mPGMA supported catalyst was used for epoxidation with structural durability and steadily reusability. Mn-NH-mPGMA as biomimetic catalyst caused a liquid-solid heterogeneous epoxidation system, and exhibited an excellent conversion with high selectivity at room temperature. Catalytic activity remained when catalyst was recycled seven times. The recycled experiments presented in this article indicated that Mn(TCPP)Cl grafted on mPGMA was suitable for efficient isolation with high recovery yield.
