The pyrolysis and thermal oxidation of pyridine have been studied in the temperature range of 700-900 °C using matrix-isolation infrared spectroscopy. The matrices employed in the studies were argon, nitrogen, and various mixtures of N2:O2 (4:1, 8:1, and 16:1). Our results indicate the formation of bipyridine and cyanomethylene as major products in pure argon and nitrogen matrices. Carbon monoxide, carbon dioxide, nitric oxide, and HOCN are observed as products in the N2:O2 matrices. Isotopic studies using 18O2 were used to confirm the identity of the observed products. Reaction mechanisms are proposed for the formation of observed products.
