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 reoxidizing agent.

Reactions of epoxides prepared from alpha-, beta-pinenes and camphene with acetic anhydride on aluminosilicate catalysts (clay K-10, zeolite beta) were investigated affording various products of skeleton I C rearrangements: mono- and diacetates with five- and six-membered rings, and also with norbornane and pinane cores.

Xanthates have been readily converted into o-chlorophenyl thioethers using a one-step procedure conducted under radical conditions. In some selected cases, these aryl thioethers were successfully oxidized to the corresponding sulfoxides and sulfenic acid elimination afforded the corresponding vinylsilanes.
