Metals in Organic Syntheses. II. The Effect of Molecular Hydrogen on the Highly Regioselective Hydrocarboxylation of Propene Promoted by a [PdCl2(PPh3)2]-PPh3 Catalyst Precursor
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 us...

| description |
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.
