An efficient Pd-catalyzed Heck reaction of aryl chlorides with olefins under mild conditions produces high yields of products with n-Bu4N+OAc- as base. Significantly, the temperature of the Heck reaction of diverse nonactivated aryl chlorides can be lowered to 80 °C. The new reaction system tolerates a wider range of olefins.
