Abstract

Smooth operators: Heck reactions of aryl chlorides were catalyzed by ligand-free palladium acetate in a molten mixture of tetraalkylammonium ionic liquids under aerobic and relatively mild conditions (see example). Deactivated electron-rich aryl chlorides reacted with a wide array of substituted alkenes under these conditions, which thus enabled the coupling of combinations of substrates that are commonly unreactive with traditional catalysts.
