Palladhim-catalyzed decarboxylative sp-sp2 cross-coupling reactions of aryl and vinyl halides and triflates with α,β-ynoic acids using silver oxide

Palladium-catalyzed decarboxylative sp-sp2 cross-coupling reactions of aryl and vinyl halides and triflates with α,β-ynoic acids using silver oxide have been developed. A variety of α,β-ynoic acids were readily decarboxylated in the presence of

Atom-efficient metal-catalyzed cross-coupling reaction of indium organometallics with organic electrophiles

The novel metal-catalyzed cross-coupling reaction of indium organometallics with organic electrophiles is described. Triorganoindium compounds (R3In) containing alkyl, vinyl, aryl, and alkynyl groups are efficiently prepared from the correspond

Palladium-catalyzed cross-coupling reactions of triorganoindium compounds with vinyl and aryl triflates or iodides

(matrix presented) A novel palladium-catalyzed cross-coupling reaction of organoindium compounds with vinyl and aryl triflates or iodides is described. The reaction proceeds for alkyl-, vinyl-, alkynyl-, and arylindium compounds in excellent yields and high chemoselectivity without any excess of the organometallic. Remarkably, indium organometallics transfer efficiently the three organic groups attached to the metal.

Palladium-Catalyzed Olefination of Vinyl Triflates

The olefination of vinyl trifluoromethanesulfonates (triflates) takes place under mild reaction conditions in polar solvents to give high yields of conjugated dienes.The reaction of 4-tert-butylcyclohexenyl triflate with Michael acceptors in the presence

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.

CARBON-CARBON BOND FORMATION BY CROSS-COUPLING OF ENOL PHOSPHATES WITH ORGANOALUMINIUM COMPOUNDS CATALYZED BY PALLADIUM(O) COMPLEX

Trialkylaluminium-mediated alkylation of enol phosphates under the C-O bond cleavage is performed stereospecifically in the presence of a catalytic amount of Pd(PPh3)4.Alkenylation and alkynylation are also described.
