Hydrated ferric chloride, FeCl3*6H2O, in a polar, hydroxylic solvent converted 2-alkylcyclopentanones directly into 2-alkyl-2-cyclopentenones on heating in the presence of air.Yields of isolated products were about 40 percent.The scope of the reaction is discussed.With cupric chloride, chloroketones were formed as intermediates, which could be dehydrochlorinated to 2-alkyl-2-cyclopentenones in similar yields.
