PALLADIUM-CATALYZED ALLYLIC OXIDATION OF OLEFINS BY t-BUTYL HYDROPEROXIDE AND TELLURIUM(IV) OXIDE
Treatment of several cyclic olefins, β-pinene, allylbenzene and estragole with palladium(II) salt in acetic acid in the presence of t-butyl hydroperoxide and tellurium(IV) oxide afforded mainly the corresponding allylic acetates.The reaction proceeded catalytically with palladium(II) salt, t-BuOOH working as a reoxidazing agent.
OAc AS A HOMOGENEOUS CATALYST FOR SELECTIVE ENONE FORMATION BY ALLYLIC OXIDATION OF OLEFINS
Treatment of several cyclic olefins and allylbenzene with a catalytic amount of OAc in acetic acid in the presence of t-butyl hydroperoxide affords the corresponding α,β-unsaturated carbonyl compounds(enones) highly selectively via an ionic pathway.
