Designing of a New Heterogeneous Polymer Supported Naphthyl-Azo Iron Catalyst for the Selective Oxidation of Substituted Methyl Benzenes

A new and interesting heterogeneous iron-anchored naphthyl-azo catalyst (PS-Fe-NAPA) has been designed using aminopolystyrene and 2-nitrosonaphthol followed by loading iron in the naphthyl-azo complex. The prepared polymer supported material has been well characterized by FE-SEM, EDAX, TGA analysis, UV–Vis, FTIR, AAS, and elemental analysis. Iron-anchored naphthyl-azo complex exhibited excellent catalytic activity for the selective oxidation of toluene and substituted toluenes containing inactive benzylic C–H bonds in presence of mild oxidant hydrogen peroxide. Additionally, PS-Fe-NAPA complex is highly recyclable up-to six times without loss of its significant catalytic efficiency.
