Abstract

The palladium-catalyzed hydroesterification of styrene derivatives is performed in a two- phase system composed of 1-n-butyl-3-methylimidazoliumtetrafluoroborate salt (ionic phase) and isopropanol/cyclohexane (organic phase). Very high regioselectivities in 2- arylpropionic esters (≥ 99.5%) are obtained using a catalytic system composed of PdCl2 (PhCN) 2,(+)-neomenthyldiphenylphosphine (NMDPP) and p-toluenesulfonic acid under ...
