Abstract

Regioselectivity in the palladium-catalysed allylic alkylation of 1-arylprop-2-enyl acetates [ArCH (OAc) CHCH2] or (E)-3-phenylprop-2-enyl acetate (PhCHCHCH2OAc) with sodium enolates of soft carbon nucleophiles is controlled by addition of a catalytic amount of lithium iodide to give lienar products [(E)-ArCHCHCH2Nu] exclusively; their branch isomers [ArCH (Nu) CHCH2] were not detected.
