Characterization of oxovanadium (IV)–Schiff-base complexes and those bound on resin, and their use in sulfide oxidation

Synthesis and Characterisation of Polymer‐Anchored Oxidovanadium(IV) Complexes and Their Use for the Oxidation of Styrene and Cumene

“…[10] Recently, Ando et al reported oxidovanadium(IV) complexes covalently bonded to Merrifield resin as a heterogeneous catalysts for the oxidation of organic sulfide selectively. [11] In continuation of our efforts on the development of polymeric supported/anchored vanadium complexes and their catalytic potential, we report herein the preparation and characterisation of polymer-anchored oxidovanadium(IV) complexes of ligands I, II and III, Scheme 1, along with their neat complexes. The catalytic potential of these complexes has been demonstrated by studying the oxidation of styrene and cumene.…”

A new oxidovanadium(IV) Schiff base complex containing asymmetric tetradentate ONN′O′ Schiff base ligand: Synthesis, characterization, crystal structure determination, thermal study and catalytic activity

“…They show 24 catalytic activity and play vital role in a variety of biochemical 25 processes such as haloperoxidation [12][13][14][15], phosphorylation [16], 26 insulin mimicking [17][18][19], nitrogen fixation [20], tumor growth 27 inhibition, and prophylaxis against carcinogenesis [17]. In addition, 28 high-valent vanadium complexes have been considered as new 29 versatile catalytic reagents for a wide range of oxidation reactions 30 [21,22], like oxidation of olefines and alcohols [23][24][25][26][27], benzene/ 31 alkylaromatic compounds [28,29], and sulfides [30][31][32] . Hydrogen atoms were mostly discernible 74 in difference Fourier maps and could be refined to reasonable 75 geometry.…”

Thermal properties of metal-metal bonded Pd(I) complexes supported onto porous Vycor glass

“…The study of supported organometallics and transition metal complexes is motivated mainly by applications as catalysts (Ando et al 2004, Kureshi et al 2004) and molecular precursors to advanced materials such as gas sensors (Alves et al 2005, Silva et al 2006, semiconductors, and metallic particles (Sunil et al 1993). In particular, heterogeneous catalysts containing Pd or Pt have been studied owing to their activity in oxidation of CO, hydrogenation, (Evrard et al 2004) and electrochemical oxidations (Yang and McElwee-White 2004).…”
