A novel peroxo‐niobophosphate 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, 31 P NMR and XPS spectra as [πC 5 H 5 N(CH 2 ) 13 CH 3 ] 2 [Nb 4 O 6 (O 2 ) 2 (PO 4 ) 2 ]·6H 2 O (PTNP). It showed high selectivity to glutaraldehyde in the catalytic oxidation of cyclopentene with aqueous hydrogen peroxide in ethanol.
