The palladium catalyzed reaction between non-symmetrical allyl acetates and sodiodimethylmalonate proceeds in high yields and enantioselectivities (up to 99percent ee) using a diphenylphosphinoaryl oxazoline ligand.The so-formed substitution products are transformed into enantiomerically enriched succinic acids and also into enantiomerically enriched γ-lactones.

Oxidation of aromatic olefins by cobalt(III) acetate in acetic acid under nitrogen gave both allylic acetates and glycol monoacetates.Disubstituted olefins were oxidized by the oxidant to give predominantly allylic acetates.Glycol monoacetates were minor products except for the case of 1-phenylisobutene which was slowly oxidized to give the corresponding glycol monoacetate.In the oxidation of tri- and tetra-substituted olefins, the yield of glycol monoacetate increased at the expense of that of allylic acetate.A mechanism, in which the reaction proceeds through a Co-co-ordinated radical kation formed by an one-electron abstraction from olefin by cobalt(III) acetate, is suggested.
