Aliphatic alcohols and water add to 1,2-dialkyl-1,4-cyclohexadienes in the presence of bis(acetonitrile)palladium dichloride to form trans-bis(5-alkoxy- and 5-hydroxy-1,2-dialkyl-1-3-η3-cyclohexenyl)palladium chloride complexes, respectively.In the alcohol series, the reaction is sensitive to the steric bulk of the alcohol nucleophile.To demonstrate synthetic utility, the derived palladium complexes in the water series were regioselectively and stereoselectively converted by subsequent methoxycarbonylation to the corresponding methyl trans-5-hydroxy-2,3-dialkyl-2-cyclohexene-1-carboxylates.

The hydrolysis of of dihydropyranyl acetals by sulfuric acid leads to cyclenones, but by the use of pyridinium p-tolenesulfonate, δ-ketoaldehydes may be isolated.These compounds do not undergo aldol condensation under these conditions.
