Microwave assisted Suzuki reaction in N-butylpyridinium salts/water systems

A solvent mixture containing an ionic liquid derived from 4-picoline ([4-MBPi][BF4]) and water was tested for the Suzuki-Miyaura reaction under microwave irradiation. This solvent system led to very high conversions and clean reactions. When compared with the other more common ionic liquid, such as [BMIM][BF4], the [4-MBPi][BF4] proved to be superior.
