Abstract
An oxidative Heck reaction enables a selective formation of complex dienes and polyenes from nonactivated terminal olefins and slight excesses of vinyl boronic esters that feature diverse functionality. The reaction proceeds via oxidative Pd(II)/sulfoxide catalysis that retards palladium-hydride isomerizations which previously limited the Heck manifold's capacity for furnishing stereodefined conjugated dienes.
