Abstract

Tetrabutylammonium nitrate is reported as an effective reusable medium, suitable reducing and stabilizing agent for the Heck coupling reaction of aryl iodides and bromides with styrene and n-butyl acrylate. The efficient phosphine-free, palladium-catalyzed homocoupling reaction of aryl iodides and bromides is also demonstrated in the presence of tetrabutylammonium nitrate. The ionic liquid, still containing Pd (0) complex, is easily recovered and reused in several runs without losing its efficiency.
