Atmosphere Dependent Photoreaction of 4-Pyridinecarboxylic Ester in Acidic Methanolic Solutions
The UV-irradiation of methyl 4-pyridinecarboxylate (1) in methanol under oxygen in the presence of sulfuric acid brings about methoxylation at the 3-position of the pyridine ring, while under nitrogen methoxylation and hydroxymethylation occur at the 2-position.The change of photoreactions of 1 caused by oxygen can not be explained either by the promotion of intersystem crossing by O2 or by the charge transfer interactions between 1 and O2.
