Abstract: A phosphine-catalyzed olefinic cross-coupling between benzyl halides and fumarates is described, which affords trisubstituted alkenes in good yields and excellent E-selectivity under metal-free conditions. Mechanistic studies suggest a catalytic cycle involving phosphorus ylide formation, Michael… read more here.
