The lithiation of substituted tosylated epoxides 7 derived from allylic sulfones with methyllithium leads to lithium (E)-3-lithio-3-tosyl-2-propenolates 5 in a stereoselective manner.The further reaction of these intermediates with different electrophilic
INDUCTION PAR LA LUMIERE DE L'OXYDATION DES COMPLEXES Η3-ALLYLPALLADIUM PAR L'OXYGENE MOLECULAIRE

, p. 731 - 739 (2007/10/02)
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.
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
