cycloheptene, gave by that reaction conjugated ketones, i.e. the corresponding 1-acetylcycloalkenes, as the only unsaturated carbonyl compounds in moderate-to-good yields. Under the same reaction conditions their 1-methyl derivatives gave mixtures of the corresponding conjugated and β,γ-unsaturated isomeric ketones in which unconjugated compounds predominate. In both cases unsaturated ketones were accompanied
The electrochemical acylation of cyclohexene, cycloheptene and their 1-methyl derivatives produces alkyl-cycloalkenyl ketones in good yields. The unsubstituted cycloalkenes give α,β-unsaturated ketones, whereas the 1-substituted derivatives yield mixtures of α,β- and β,γ-unsaturated ketones in which the latter products are predominant.
