概要
- 論文の詳細を見る
The UV-irradiation of 2-pyridinecarbonitrile(<B>1</B>) in methanol and in ethanol brings about the replacement of the cyano group by the hydroxyalkyl groups and the replacement of the ring hydrogen by the alkoxyl group. Free base-form of <B>1</B> in ethanol undergoes exclusively photo-hydroxyethylation, while the pyridinium form of <B>1</B> in ethanol undergoes both photo-hydroxyethylation <I>via</I> a singlet excited state and -ethoxylation <I>via</I> a singlet-excited state complex, which is quenched by the electron transfer from the aromatic hydrocarbons to the excited complex.
