Highly stereospecific, palladium-catalyzed cross-coupling of alkenylsilanols

[GRAPHICS] Alkenylsilanols bearing methyl ((E)-1 and (Z)-1) or isopropyl ((E)-2 and (Z)-2)) substituents are converted to disubstituted alkenes by a palladium(0)-catalyzed cross coupling reaction with aryl or vinyl iodides in the presence of tetrabutylammonium fluoride or hydroxide, Yields and stereoselectivities are generally high, and the reaction is compatible with a wide range of functional groups.
