Experimental and computational studies on the [3,3]- and [3,5]-sigmatropic rearrangements of acetoxycyclohexadienones: A non-ionic mechanism for acyl migration
Flash vacuum pyrolysis studies of substituted 6-acetoxy-2,4- cyclohexadienones (3 and 10) from 300 to 500 C provide strong experimental evidence that direct [3,5]-sigmatropic rearrangements in these molecules are favored over the more familiar [3,3]-sigma

Light-induced Reactions, XIV. Rules for Determining Spectra of 2,4-Cyclohexadien-1-ones
2,4-Cyclohexadien-1-ones of formula types 1 to 5 (cf.Fig. 1) provide basic values and positional increments for UV and 13C NMR spectra.These parameters allow to distinguish between constitutional isomers belonging to one and the same column of the graph of Fig. 1.It has become possible, e.g., to identify clearly the constitutional isomers 6 and 8 or 12 and 14, respectively.
