2-Nitrofuran and 2-nitropyrrole are converted on irradiation into the previously unknown 3-hydroxyiminofuran-2(3H)-one and 3-hydroxyiminopyrrol-2(3H)-one by a process analogous to that reported for the photorearrangement of certain conjugated nitroalkenes. 2-Methyl-5-nitrofuran undergoes an identical rearrangement, whereas 3-methyl-2-nitrofuran is converted into 5-hydroxyimino-3-methylfuran-2(4H)-one.(E 3400) aiid 315 nm (8100).15 Irradiation of a solution in acetone with a medium-pressure mercury arc sur-1

K epz t ) Summary Irradiation of 2-nitrocycloheptanone in ethanol or acetonitrile leads to the formation of N-hydroxy-2,sdioxoazacyclo-octane ; analogous reactions are reported for 2-nitrocyclohexanone and a-nitrocamphor.
