Abstract

The hydrocarboxylation of propene with MeOH or n-BuOH promoted by [PdCl2(PPh3)2] as catalyst precursor in combination with added PPh3, occurs with high selectivity towards the linear ester, particularly at low PCO. The yield is almost independent of PCO (in the range experienced, 13-95 atm) when using MeOH and decreases on decreasing PCO with n-BuOH. With this alcohol the yield can be increased in the presence of molecular hydrogen, while maintaining high the selectivity and without aldehyde formation; this hydrogen effect is observed also with MeOH when using toluene as solvent.
