Abstract
E-mail: cuigdut@yahoo.com.cnReceived April 8, 2013, Accepted May 13, 2013A convenient Rh-catalyzed C-H arylation of imidazo[1,2-a]pyridines with a variety of aryl halides or triflateshas been reported. This process afforded a range of biaryl compounds in excellent yields and showed highactivity and broad scope. Key Words : Rhodium catalyst, Aryl halides, Regioselective arylation, Imidazo[1,2- a]pyridines, TriflatesIntroductionHeteroaromatics bearing aryl-heteroaryl bond are alwaysas one of the most important structural units frequentlyfound in biological compounds, natural products, materialschemistry, ligands.
