Selective dibenzoylation of biphenyl to 4,4'-dibenzoylbiphenyl over H-Al-MCM-41
Dibenzoylation of benzoyl chloride in the presence of mesoporous H-A1-MCM-41 forms the biphenyl 4,4'-dibenzoylbiphenyl (DB) with 100% selectivity. 27A1 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 a...
