Abstract Two oxidovanadium(IV) complexes [VO(xbp‐sc)] ( 1 ) and [VO(xbp‐tc)] 2 were prepared using hydrazine‐ether mixed functionality ligands Hxbp‐sc I Hxbp‐tc II ), respectively. Complexes carefully grafted separately into imidazole‐modified chloromethylated polystyrene (Ps−Im) unmodified (PS−Cl) beads. Successfully anchored vanadium Ps−Im‐[VO(xbp‐sc)] 3 Ps−Im‐[VO(xbp‐tc)] 4 Ps‐[VO(xbp‐sc)] 5 Ps‐[VO(xbp‐tc)] 6 tested for their catalytic potential towards the oxidation of aliphatic alcohols in presence hydrogen peroxide. Polymer‐grafted catalysts display excellent substrate conversion compared to most recent reports good recyclability up three cycles without losing much reactivity. High TOF values range 183–591 h −1 are observed supported – . The highest is ethanol (63–97 %) under optimized reaction conditions. Mainly, better obtained with polymer beads than those on ). Moreover, semicarbazide group ligand framework show reactivity alcohol fewer carbon atoms. On contrary, longer chains oxidize more easily catalyst thiosemicarbazide frameworks
