Molecular oxygen, oxidation organometallic compound

By coincidence, the oxygen problem is related to our present question. In the late 18th century, molecular oxygen (02) was a revolutionary discovery for chemists because of its involvement in oxidation, and because of the demonstration that a gas reacts chemically with liquids and solids. On the other hand, nitrogen gas (N2) is, as was already known at that time, inert towards most other chemicals, in particular towards all purely organic compounds (i. e., not organometallic compounds).

With regard to the susceptibility of many organometallics to aerial oxidation, it must be remembered that most compounds containing C-H bonds are thermodynamically unstable with respect to oxidation by molecular oxygen to produce water and carbon dioxide. The mechanisms whereby (for example) many alkyls are spontaneously flammable in air are necessarily difficult to determine the mechanisms involved in the combustion of hydrocarbons are still incompletely understood. Suffice it to say that the kinetic stability of ER to air seems to be low where E is of low electronegativity. 

Oxovanadium(V) compounds are potential Lewis acids with oxidation ability to induce one-electron oxidation reactions based on their characteristics. Oxidation capability and redox potential are effectively controlled by the substituent of oxovanadium(V) compounds. A catalytic system is allowed to be realized by the redox interaction with molecular oxygen. The oxidative ligand coupling proceeds via the intermetallic interaction between vanadium species and main-group organometallics.
