Abstract

The palladium-catalyzed cross-coupling reaction of potassium alkenyltrifluoroborates with aryl and heteroaryl halides and triflates proceeds readily with moderate to excellent yields. The alkenyl cross-coupling reaction can generally be effected using 2 mol % of PdCl2(dppf)ĚCH2Cl2 as catalyst in i-PrOH-H2O in the presence of t-BuNH2 as the base.
