摘要

A novel peroxo-nioboplosphate was synthesized for the first time and used as a catalyst in the oxidation reaction of cyclic olefins with aqueous hydrogen peroxide to prepare dialdehydes. The catalyst was characterized by elemental analysis,thermographic analyses, IR, UV/vis, 31P NMR and XPS ~ as [ π-C5H5N(CH2)i3CH3 ]2 [Nb406 (O2)2 (PO4)2] ·6H20 (PTNP). It showed high selectivity to glutaraldehyde in the catalytic oxidation of cyclopentene with aqueous hydrogen peroxide in ethanol.
