Abstract
Highly selective synthesis of 1-substituted (E)-buta-1,3-dienes via palladium-catalyzed Suzuki–Miyaura cross-coupling of (E)-alkenyl iodides with 4,4,5,5-tetramethyl-2-vinyl-1,3,2-dioxaborolane (1) is reported. The vinylboronate pinacol ester (1) acts as a vinyl building block to show high chemoselectivity for the Suzuki–Miyaura pathway versus Heck coupling in the presence of biphasic conditions (Pd(PPh3)4, aqueous K2CO3, toluene and ethanol).
