The photorearrangement of 2-nitrofuran and 2-nitropyrrole
Abstract
2-Nitrofuran and 2-nitropyrrole are converted on irradiation into the previously unknown 3-hydroxyimino-2-oxo-2,3-dihydrofuran and 3-hydroxyimino-2-oxo-2,3-dihydropyrrole by a process analogous to that reported for certain conjugated nitroalkenes.
