Synthesis,Characterization,Reactivity and Antibacterial Activity of New Peroxovanadium(V)Complexes Anchored to Soluble Polymers(abstract)

摘要

There has been a continuous upsurge in interest in polymer anchored transition metal complexes from viewpoint of designing effective redox catalysts as well as modeling of complex processes in bio-systems.Vanadium and its compounds including peroxovanadates have been for the past several years object of intense investigation,owing to their role as oxidation catalyst,and biochemical relevance.Studies on synthetic peroxovanadate complexes as functional and structural models of bromoperoxidase,the enzyme involved in the biosynthesis of a variety of naturally occurring brominated products,have been immensely useful in elucidating the details of mechanism of action of the enzyme which is yet to be fully understood.A few peroxometal systems including one pV compound,supported on insoluble cross-linked polymers were prepared recently which were reported to exhibit good activity as catalytic or stoichiometric oxidant in organic oxidations.However,there appears to be no information available on peroxometallites bound to soluble polymers or use of such material as oxidative agents.The utility of soluble polymers as supports in organic chemistry is increasingly being recognized in recent years.Moreover,there has been considerable contemporary interest in development of pharmaceutical formulations consisting soluble polymers.
