Abstract

Organic reactions catalyzed by palladium, except Pd/C, are conducted with heating by microwave energy. The preferred inorganic reactions involved are coupling reactions in which a new carbon-carbon bond is formed. Preferred reactions are the Heck, Stille and Suzuki reaction. The method provides high yields in very short reaction times.
