Synthesis of transition-metal complexes by cycloaddition and their application in catalysis

Abstract

The present thesis focuses on design and syntheses of mono- and dinuclear copper and cobalt tetrazolato complexes by metal mediated [2+3] cycloaddition reaction between copper and cobalt bound azide [Cu(bipy)(N3)2]n , [Cu(phen)(N3)2]n and [Co(Me2en)2(N3)2] {bipy=2,2 bipyridyl, phen=1,10 phenanthroline and (Me2en)2=N,N’ dimethylethylenediamine} and different organonitriles e.g. benzonitrile, 4-cyanobenzonitrile and 4-pyridinebenzonitrile. Catalytic properties of the synthesized copper tetrazolato complexes have been examined which act as a homogeneous catalysis for the oxidation of benzene into phenol, benzoquinone and catechol and interactions of cobalt complexes with bovine serum albumin (BSA) are also explored.
