PROCESS FOR THE ALKOXYCARBONYLATION OF FUNCTIONALIZED ALKENES |
| 摘要 |
This invention relates to a process for the alkoxycarbonylation of carboxylic acid functionalized alkenes or esters thereof, said process comprising: (a) reacting (i) a carboxylic acid functionalized alkene or ester thereof; (ii) a catalyst system comprising a source of Pd and a ligand, (iii) a source of anions derived from an acid with a pKa<3, (iv) carbon monoxide, and (v) a hydroxylgroup comprising compound, under conditions wherein an ester carbonylation product is produced, whereby the process is carried out in the initial presence of an ester carbonylation product. The presence of the ester carbonylation product results in stabilization of the catalyst system and prevents the formation of Pd black. |

1. A process for alkoxycarbonylation of carboxylic acid functionalized alkenes and/or esters thereof, said process comprising:
(a) reacting (i) a carboxylic acid functionalized alkene and/or ester thereof; (ii) a catalyst system comprising a source of Pd and a ligand, (iii) a source of anion derived from an acid with a pKa<3, (iv) carbon monoxide, and (v) a hydroxylgroup comprising compound, under conditions wherein an ester carbonylation product is produced, whereby the process is carried out in initial presence of an ester carbonylation product. |
