Abstract
<jats:title>Abstract</jats:title> <jats:p>Asymmetric 1,4-addition of [ArBF3]K to cyclic and acyclic enones was carried out in aqueous methanol in the presence of a chiral phosphine-dicationic palladium(II) catalyst. A palladium complex of (S,S)-dipamp gave optically active β-arylketones of up to 96 % ee for 2-cyclohexenone and 2-cycloheptenone. A palladium-(S,S)-chiraphos complex resulted in 82–97 % ee for 2-cyclopentenone and acyclic enones.</jats:p>
