摘要

Dibenzoylation of benzoyl chloride in the presence of mesoporous H-Al-MCM-41 forms the biphenyl 4,4'-dibenzoylbiphenyl (DB) with 100% selectivity. ~(27)Al MAS NMR, pyridine adsorption and XRD data reveal that both Bronsted and Lewis acidities play a role in the production of DB and the catalytic activity is dependent on the structure of the mesoporous H-Al-MCM-41.
