Model dioxovanadium(V) complexes through direct immobilization on polymer support, their characterization and catalytic activities

Dioxovanadium(V) complexes, K[VO2(sal-inh)(H2O)] and K[VO2(sal-bhz)(H2O)] (where H2sal-inh = Schiff base derived from salicylaldehyde and isonicotinoylhydrazide, and H2sal-bhz = Schiff base derived from salicylaldehyde and benzoylhydrazide) have been reacted with polymer bound imidazole (PS-im) to give polymer-supported complexes, abbreviated as PS-K[VO2(sal-inh)(im)] and PS-K[VO2(sal-bhz)(im)]. Characterization and catalytic potential of these complexes for the oxidative bromination of salicylaldehyde, oxidation of methyl phenyl sulfide and benzene using 30% H2O2 as an oxidant have been reported.
