摘要：

In this letter, an overview of the literature on the reaction mechanism of the reduction of nitric oxide by hydrocarbons in presence of oxygen is given. It is followed by a discussion of some organic chemistry literature. A new reaction mechanism is proposed which combines two of the reaction mechanisms proposed in the literature and involves a nitroso-intermediate which initiates a radical chain mechanism which leads to the disproportionation of nitric oxide into nitrogen and nitrogen dioxide. Finally, the reaction mechanisms proposed until now are compared.
