In this study, a simple and practical method for preparation of new ionic liquids is described. These ionic liquids react with palladium (II) to produce palladium (0) catalyst which is proved by ultra-violet spectroscopy. The use of this new system in Pd-catalyzed Heck reaction provides a useful protocol for the efficient carbon-carbon bond formation in the absence of base. Also, the use of these ionic liquids as reducing agent, ligand and reaction media in base- and copper-free palladium catalyzed sonogashira reaction of aryl halides is explained.
