addition to the ring nitration and side-chain nitrooxylation products. Chromatographic separation over silica gel followed by spectral investigation established the structures of these nitro-ketones to be 2,3,4,6-tetramethyl-5,6-dinitro-3-cyclohexen-1-one and 2,4,6-trimethyl-3-ethyl-5,6-dinitro-3-cyclohexen-1-one respectively. The mechanistic interpretation of their formation was briefly discussed
