A short and practical arylation of imidazo[1,2-a]pyridine and imidazole derivatives with aryl halides or aryl boronic acids as coupling partners was successfully carried out using phosphine-free (SIPr)Pd(allyl)Cl as the catalyst [SIPr: (N,N’-bis(2,6-diisopropylphenyl)-4,5-dihydroimidazol-2-ylidene)] ((SIPr)Pd(allyl)Cl complex). 3,6-disubstituted imidazo[1,2-a]pyridine and 5-substituted imidazole compounds were obtained in good to excellent yields in only 1h under microwave-assisted C-H arylation and Suzuki-Miyaura coupling reaction conditions.
