Carbonylation process for the production of aromatic acids or esters |
摘要 |
This invention relates to a novel carbonylation process for the production of aromatic carboxylic acids or esters of aromatic. More particularly, this invention relates to a process for the carbonylation of aromatic iodides or bromides with carbon monoxide in the presence of a palladium catalyst promoted with a Group VIB carbonyl and in the presence of an alcohol or water in a base reaction medium having a pKa greater than about 8. When the alcohol is used the product is the ester. When water is used the product is the carboxylic acid.
