Interaction of NO with Organic Compounds

The fast reaction between NO and methyl radical has been studied repeatedly over the years [6-10]. The initial product of the interaction of methyl radical and NO is nitroso methane isomerising next into formaldoxime  

The features of the mechanism of the reaction between methyl radical and NO were explained adequately on the basis of the formation and subsequent decomposition of formaldoxime [4]. This compound was first identified among the products of the thermal decomposition of di- butyl peroxide in an atmosphere of NO at 225 C 

Acetone and a stable dimer of nitroso methane are major products of the photodecomposition of butyl nitrite at 25 °C [12]. It was suggested that dimer formation from nitroso methane monomer follows the primary process  

The product composition indicates the formation of intermediate methyl radicals and NO which recombine. Nitroso methane dimers have cis and trans-isomer forms 

The IR technique has been used to determine directly the concentration of nitroso methane formed in the photolysis of azomethane in NO [9]. The following simple mechanism adequately describes the results obtained
