Individual Use

Arylboronic acid and DMAPO cooperatively catalyse the dehydrative condensation reaction between carboxylic acids and amines to give the corresponding amides under azeotropic reflux conditions. This cooperative use is much more effective than their individual use as catalysts.

Cooperative Catalysis

A nickel/visible light photoredox co-catalyzed decarboxylative thiolation reaction of carboxylic acids has been developed. This odorless sulfenylation reaction proceeded well via a nickel/photoredox cooperative catalysis pathway under very mild conditions.
