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