Potassium Organotrifluoroborates: New Partners in Palladium-Catalysed Cross-Coupling Reactions

Abstract

The preparation of various potassium organotrifluoroborates bearing either aryl, alkenyl, or alkynyl substituents is described. These stable salts are shown to be very efficient partners in palladium-catalysed cross-coupling reactions with arenediazonium salts, affording biaryl and styrene derivatives in high yields.
