ASYMMETRIC INDUCTION IN THE PALLADIUM-CATALYZED SULFONYLATION OF ALLYLIC SULFINATES AND ACETATES WITH CHIRAL PHOSPHINE LIGANDS

Treatment of allylic (+/-)-p-toluenesulfinates with tetrakis-(triphenylphosphine) palladium in the presence of chiral phosphine ligands underwent allylic sulfinate-sulfone rearrangements to give the corresponding optically active allylic sulfones in high

"Syn-Effect" in the Desilylation Reaction of γ-Silylated Allylic and Vinylic Sulfones

The desilylation reaction of γ-silylated allylic sulfones was found to proceed through γ-silylated (E)-vinylic sulfones to afford the corresponding allylic sulfones by treatment with DBU and H2O. The Z/ E ratio of the resulting allylic sulfones varied according to the γ-substituents of the γ-silylated sulfones. This stereo-chemical outcome was rationalized by "syn-effect".

INDUCTION PAR LA LUMIERE DE L'OXYDATION DES COMPLEXES Η3-ALLYLPALLADIUM PAR L'OXYGENE MOLECULAIRE

Irradiation at λ=366 nm of oxygenated solutions of η3-allylpalladium complexes leads to unsaturated carbonyl compounds.Substitution of the η3-allyl ligand by an electron withdrawing group could induce a regioselective oxidation of the allylic position farthest from this group.The efficiency of these reactions is sensible to the nature of the solvent.
