This book introduces readers to the fundamentals of oxygen atom transfer reactions. It also gives mechanistic insights into the redox processes occurring through the oxygen atom transfer reactions. It also includes information about catalytic activation of oxygen through enzymes and oxo-metallic complexes. All topics are explored in separate chapters.<br/> <br/> <br/> <br/>Key features:<br/> <br/>- reviews the basic mechanisms in redox processes involving oxo-atom transfer reactions.<br/> <br/>- presents progress in the biomimetic activation of dioxygen related to the catalytic oxidations by synthetic metal organic complexes.<br/> <br/>- covers an important class of metal-organic compounds - nickel-oxygen species - generated in catalytic oxidation processes as oxygen atom transfer agents.<br/> <br/>- explains the mechanistic aspects of the heterogeneous photochemical redox processes via oxo-atom transfer reactions<br/> <br/>- provides references for further reading<br/> <br/> <br/> <br/>It is a reference for both professional scientists in the fields of chemistry, biology and applied sciences, and for graduate and undergraduate students interested in understanding reaction mechanisms involving oxygen.
