Process for preparing carboxylic acids by carbonylation of ethers and thioethers |
| abstract |
A new process for preparing aryl-substituted aliphatic carboxylic acids is provided. Aryl-substituted aliphatic ether or thioether compound is reacted with carbon monoxide in aqueous conditions at a temperature between about 25° C. and about 200° C. An acid such as hydrochloric acid may be added. As catalyst, a mixture of palladium or a palladium compound and a copper compound with at least one acid-stable ligand are present. |
