[摘要]:p-Allylic substitution of allyl esters with sodium arylsulfinate was (PS-PEG) resin-supported phosphine-palladium complex in water as single reaction medium under heterogeneous conditions to give allyl sulfones in good to high yields. Catalytic asym. allylic substitution of cycloalkenyl esters also took place in water using a PS-PEG resin-supported chiral imidazoindolephosphine-palladium complex to give cycloalkenyl sulfones with ?1% ee.
