摘要

A mixture of benzoic anhydride, phthalic anhydride and benzene is formed by the reaction of bromo-or chlorobenzene, carbon monoxide and alkali metal carbonates or orthophosphates in the presence of nickel tetracarbonyl. Under optimum conditions, phthalic anhydride is obtained in 75% conversion. Benzoic anhydride may be the immediate precursor of phthalic anhydride, as shown by its conversion to phthalic anhydride and benzene by heating with ...
