Photochemical transformations. Part 11. Photorearrangement of 1-(2-pyridyl)- and 1-(3-pyridyl)-2-nitropropenes
Abstract
Pyrex-filtered irradiation of 1-(2-pyridyl)- and 1-(3-pyridyl)-2-nitropropene in acetone solution gives 1-(2-pyridyl)- and 1-(3-pyridyl)-1-hydroxyiminopropan-2-one, respectively, in high yield.
