In Suzuki-Miyaura coupling, Z-alkenyl halides can easily undergo Z-to-E isomerization, the extent of which is dictated mainly by the ligand on palladium. Pd(P(o-Tol)3)2 as catalyst of choice leads to the desired products under mild conditions and in high yields that, in most cases, retain their Z-olefin geometry.
