15N-Labeling Study of the Rearrangement of r-2,4-Dichloro-t-6-hydroxy-3,6-dimethyl-2,T-5-dinitrocyclohex-3-enone to 4-Chloro-c-6-hydroxy-3,6-dimethyl-r-5-nitro-cyclohex-3-ene-1,2-dione

Abstract

Reaction of hydroxy dinitro ketone (15) in solution gives the α-diketone (16). This reaction has been shown, by means of 15N n.m.r. spectroscopy, to occur via C2-epimeric nitro nitrites (19) and (20). X-Ray crystal analyses are reported for hydroxy dinitro ketone (15) and α-diketone (16).
