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.

Aryl Boronic Acid

A green synthesis of variously substituted biphenyl carboxylic acids was achieved through Suzuki–Miyaura cross-coupling of a bromobenzoic acid with an aryl boronic acid using a water-soluble fullerene-supported PdCl2 nanocatalyst (C60-TEGs/PdCl2). Yields of more than 90% were obtained at room temperature in 4 h using 0.05 mol% catalyst and 2 equiv. K2CO3.
