Abstract

The palladium-catalyzed cross-coupling reaction of potassium vinyltrifluoroborate with aryl electrophiles can generally be effected using 2 mol % of PdCl2 and 6 mol % of PPh3 as a catalyst system in THF/H2O with Cs2CO3 as a base. Good yields are obtained in the presence of various functional groups.
