概要

• 論文の詳細を見る

• The rate of photo-methoxylation of methyl 2-pyridinecarboxylate(<B>1</B>) in acidic methanol is accelerated by 4-substituted pyridines and their analogs, 4,4′-bipyridine and pyrazine. The photo-methoxylation of <B>1</B> is not promoted by triplet sensitizers, electron donors, or electron acceptors. Detailed analyses on the <B>1</B>–4-pyridinecarbonitrile(<B>3</B>) system including wavelength dependence lead to a mechanism for the promotion <I>via</I> an excited complex formed from an excited <B>1</B> and <B>3</B> in the ground state.
