Reversible Binding of Dioxygen by a Non-Transition-Metal Complex

摘要

For decades,reversible binding of molecular oxygen to various organic and coordination compounds has remained one of the fundamental problems in chemistry because it concerns a number of biochemical and catalytic processes that occur with the participation of molecular oxygen.Numerous examples of reversible binding of molecular oxygen to transition-metal complexes,thus modeling the active centers in biological oxygen carriers,are known.In these complexes,the binding of oxygen is accompanied,in many cases,by the transfer of electrons from the metal center to the oxygen molecule,and thus the oxidation state of the metal atom changes.
