Abstract
The gaseous photolysis of 2-picoline N-oxide was carried out by irradiation with the 3261A (Cd 3P1) or 2537A (Hg 3P1) resonance lines corresponding to an n-π* or a π-π* absorption of this substance, respectively.In the case of 3261A irradiation, the major product was 2-pyridinemethanol, whose quantum yield showed a marked temperature-dependence. The activation energy necessary for the production of 2-pyridinemethanol was estimated to be about 3.4 kcal. mol−1.On the other hand, the photolytic products at 2537 A irradiation were 2-picoline and other decomposition products and polymers. The quantum yield of 2-picoline showed a marked temperature-dependence, which may be attributed to the interaction between the 2-methyl group and the N→O group. The activation energy necessary for the production of 2-picoline was estimated to be about 1.1 kcal. mol−1.
