摘要：

The catalyst system, montmorillonite-diphenylphosphinepalladium(II) chloride complex, HCl-NMDPP, afforded the corresponding branched ester quantitatively at 125 degrees C and 45 atm of CO pressure. The high catalytic activity (substrate/Pd = 500) demonstrates its potential use on commercial scale although the enantioselectivity is not satisfactory. In contrast to previous studies, bulky bidentate ligands were also effective because of the higher interlamellar spacings of the catalyst.
