PROCESS FOR PREPARING CARBOXYLIC ACIDS BY CARBONYLATION OF ETHERS AND THIOETHERS |
摘要 |
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 25 DEG C and 200 DEG 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.
