Process for preparing aryl-substituted aliphatic carboxylic acids and their alkyl esters |
| abstract |
A new process for preparing aryl substituted aliphatic carboxylic acids or their alkyl esters is provided. A 1-aryl substituted olefin is reacted with carbon monoxide in the presence of water or an alcohol at a temperature between 25 °C and 200 °C. An excess of several moles of water or alcohol is preferred. An acid such as hydrochloric acid may also be added. As catalyst, a mixture of a palladium compound and a copper compound with at least one acid-stable ligand is present. |
