The development of new strategies for the synthesis of biomass-based nonprecious metal heterogeneous catalysts has recently received great interest from chemists because of the advantages of these catalytic systems being sustainable, low cost and green. An expanded corn starch-supported CuBr catalyst (ECS-SB-CuBr) has been successfully prepared and well characterized using Fourier transform IR spectroscopy, thermogravimetric anal., powder X-ray diffraction, XPS and SEM/energy-dispersive X-ray spectroscopy. Further, ECS-SB-CuBr was used as a heterogeneous catalyst for the selective oxidation of 5-hydroxymethylfurfural (HMF) into 2,5-diformylfuran (DFF) and a full HMF conversion is obtained with 98% DFF yield in acetonitrile under ambient pressure of dioxygen at 50°. The catalyst also showed good reusability, could be easily recovered through filtration and washing and was reused in at least six consecutive runs with virtually no loss of catalytic performance. The results came from multiple reactions, including the reaction of Cupric bromide(cas: 7789-45-9Related Products of 7789-45-9)
Some reported applications of Cupric bromide(cas: 7789-45-9) are: catalyst in cross coupling reactions; co-catalyst in Sonogashira coupling; lewis acid in enantioselective addition of alkynes.Related Products of 7789-45-9
