Abstract:

The Suzuki-Miyaura reaction, the palladium catalyzed coupling of organic halides and organic compounds of boron, is one of the most efficient alternatives to the formation of carbon-carbon bonds, with success in the synthesis of biaryls. Consequently, the interest in creating systems that are efficient for this reaction is an area of intense research efforts. Ionic Liquids have been increasingly studied, as an environmentally acceptable alternative to replace the use of organic solvents. These substances have an important advantage that comes from their ionic characteristics such as high density and low vapor pressure. In this paper we wish to present the results of the Suzuki-Miyaura coupling reaction promoted by microwave irradiation (MW) using ionic liquids derived from different pyridinium cations (Fig. 1), assisted by microwave irradiation (MW).
