α,β-Unsaturated carbonyl compounds underwent regiospecific iodosulphonylation with toluene-p-sulphonyl iodide or sodium toluene-p-sulphinate and iodine to afford products (2), which were stereoselectively dehydroiodinated by triethylamine to give β-sulphonyl derivatives (3).The reactivity of compounds (3) as cationic β-acylvinyl equivalents, tested with amines or thiophenol, gave compounds (4) resulting from a displacement reaction.

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.
Palladium-catalyzed allylic oxidation of 1-(p-toluenesulfonyl)-2-propene and 1-(trimethylsilyl)-1-(p-toluenesulfonyl)-2-propene

, p. 113 - 120 (2007/10/02)
The course of palladium-catalyzed oxidation of a terminal alkene by t-BuOOH or by O2/H2O is greatly modified when the allylic carbon bears a p-toluenesulfonyl substituent, and allylic oxidation results.Mechanistic explanations of this observation are prop
OXIDATION REGIOSELECTIVE DE SULFONES ALLYLIQUES CATALYSEE PAR LE PALLADIUM ET LA LUMIERE: FORMATION D'ALDEHYDES ET ALCOOLS α,β-ETHYLENIQUES β-SULFONYLES
Muzart, J.,Riahi, A.,Pete, J. P.
, p. 269 - 280 (2007/10/02)
The irradiation of oxygenated solution of allyl sulfones containing small amounts of palladium trifluoroacetate led to regioselective oxidation of the allylic position furthest from the electron-withdrawing group.The efficiency of this reaction increased
PHOTOOXYDATION REGIOSELECTIVE DE COMPLEXES η3-ALLYLPALLADIUM: ACCES A DES COMPOSES CARBONYLES α,β-INSATURES FONCTIONNALISES EN γ
Muzart, J.,Pale, P.,Pete, J. P.
, p. 4567 - 4568 (2007/10/02)
Irradiation of oxygenated solutions of η3-allylpalladium complexes, formed from alkenes substituted in α or β-position by an electron-withdrawing group, leads to a regioselective oxidation of the allyl group.
