Abstract: The zwitterionie title compounds 5a-d are obtained by FVT of picolinoylacetates 3a-d. Compounds 5a-d undergo nucleophilic addition reactions by C-N bond cleavage to afford pyridine derivatives 6-12. The thermal and photochemical ring opening of 5a to the ketene valence isomer 4a is demonstrated by matrix isolation IR spectroscopy and supported by excellent agreement with DFT calculations. © The Royal Society of Chemistry 2000.
