Oxidation of Benzyl Alcohols by Polymer Supported V(IV) Complex Using O2

Polymer supported and unsupported oxovanadium(IV) complexes with 2,6-bis(benzimidazolyl)pyridine were synthesized and characterized by elemental analyses, molar conductance, magnetic moment measurements, electronic, IR, ESR spectral studies, LC–MS and thermogravimetric analysis. Based on the results, an octahedral geometry was intended around V(IV) complexes. Polymer-anchored V(IV) complex catalyzed the oxidation of benzyl alcohols in acetonitrile with O2 as an oxidant. Several parameters were differed to optimize the reaction conditions. Under the optimized reaction conditions, benzyl alcohol oxidation confirmed 96% conversion with 100% selectivity towards benzaldehyde. The developed catalyst revealed excellent benzyl alcohol oxidation at moderate temperature in presence of oxygen making the reaction simpler and environmentally benign. The polymer anchored V(IV) complex showed excellent recyclability as compared to its unsupported analogue. Graphical Abstract: [Figure not available: see fulltext.].

A bioinspired construct that mimics the proton coupled electron transfer between P680?+ and the Tyrz-his190 pair of photosystem II

A bioinspired hybrid system, composed of colloidal TiO2 nanoparticles surface modified with a photochemically active mimic of the PSII chlorophyll-Tyr-His complex, undergoes photoinduced stepwise electron transfer coupled to proton motion at the phenolic site. Low temperature electron paramagnetic resonance studies reveal that injected electrons are localized on TiO2 nanoparticles following photoexcitation. At 80 K, 95% of the resulting holes are localized on the phenol moiety and 5% are localized on the porphyrin. At 4.2 K, 52% of the holes remain trapped on the porphyrin. The anisotropic coupling tensors of the phenoxyl radical are resolved in the photoinduced D-band EPR spectra and are in good agreement with previously reported g-tensors of tyrosine radicals in photosystem II. The observed temperature dependence of the charge shift is attributed to restricted nuclear motion at low temperature and is reminiscent of the observation of a trapped high-energy state in the natural system. Electrochemical studies show that the phenoxyl/phenol couple of the model system is chemically reversible and thermodynamically capable of water oxidation. Copyright
