Talukdar, Hiya; Gogoi, Sandhya Rani; Saikia, Gangutri; Sultana, Sazida Yasmin; Ahmed, Kabirun; Islam, Nashreen S. published the artcile< A sustainable approach towards solventless organic oxidations catalyzed by polymer immobilized Nb(V)-peroxido compounds with H2O2 as oxidant>, SDS of cas: 699-12-7, the main research area is peroxidoniobium complex immobilized polystyrene divinylbenzene resin catalyst preparation; epoxide preparation; styrene oxidation niobium catalyst; sulfone preparation; thioether oxidation niobium catalyst.
New heterogeneous catalysts comprising of peroxidoniobium(V) complexes immobilized on amino acid grafted cross-linked poly(styrene-divinylbenzene) resin was developed. Results of FTIR, Raman, NMR, XPS, XRD, EDX, SEM, BET, TGA, and elemental anal. confirmed the successful anchoring of triperoxidoniobium(V), [Nb(O2)3]- species to the host polymer via the pendant amino acid groups. The supported catalysts exhibited excellent performance in epoxidation of styrene and a range of cyclic and terpenic compounds under environmentally acceptable solvent-free condition, with aqueous H2O2 as oxidant. The catalytic protocols provided excellent conversion to the desired epoxide (up to 100%) with selectivity > 99%, TON as high as 1000, and high H2O2 utilization efficiency (92-97%). Moreover, the catalysts efficiently facilitated chemoselective solvent-free oxidation of a variety of thioethers to sulfones at room temperature Simple operational strategy, easy recyclability for multiple reaction cycles with the consistent activity-selectivity profile are the addnl. significant attributes of the developed catalytic processes.
