Convergence of mechanistic pathways in the palladium(0)-catalyzed cross-coupling of alkenylsilacyclobutanes and alkenylsilanols

[GRAPHICS] Alkenylsilacyclobutenes and alkenylsilanols react in palladium-catalyzed cross coupling reactions via the same intermediate, produced in situ upon treatment of either starting material with tetrabutylammonium fluoride.
