Reaction of F Atoms with Methyl Nitrite. Infrared Spectroscopic Evidence for the Stabilization of FON in an Argon Matrix

Article abstract of DOI:10.1021/j150642a035

When the products of the reaction between F atoms formed in a microwave discharge and methyl or methyl-d₃ nitrite are frozen in a large excess of argon at 14 K, prominent absorptions of FNO appear in the infrared spectrum of the solid deposit, demonstrating that NO abstraction occurs.Two absorptions previously attributed to FON are also very prominent, supporting the identification of that isomer, but the assignment of the NO-stretching fundamental of FON was not confirmed.The appearance of infrared absorptions of isolated and hydrogen-bonded HF indicates that the more exothermic reaction channel involving H-atom abstraction also occurs.The absorptions of H2CO and NO, products of the decomposition of CH2ONO, are prominent, with indirect evidence that a small concentration of CH2ONO may have been stabilized.Factors influencing the relative contributions of the two observed F-atom reaction channels are considered.
