CROSS-COUPLING REACTION BETWEEN ENOL PHOSPHATES AND ORGANOALUMINIUM COMPOUNDS IN THE PRESENCE OF PALLADIUM(0) CATALYST.

The title reaction in the presence of a catalytic amount of tetrakis(triphenylphosphine)palladium(0) affords alkylative coupling products in good to excellent yields in 1,2-dichloroethane at room temperature. This coupling reaction under C(sp**2)-O cleavage proceeds stereospecifically. The reaction does not affect a coexisting vinyl sulfide group. This feature enables 1,2- and 1,3-carbonyl transposition with or without alkylation via phenylthio-substituted enol phosphates.

Pd(O) PROMOTED ALKYLATION OF ENOL PHOSPHATES WITH ORGANOALUMINIUM COMPOUNDS AND ITS SYNTHETIC APPLICATIONS

Keto carbonyl 1,2- and 1,3-transpositions with and without alkylation of the substrate are described together with ketone synthesis from thiocarboxylic S-ester.
