✦ Synopsis

The activity of [Pd{C 6 H 4 (CH 2 N(CH 2 Ph) 2 )}(m-Br)] 2 complex was investigated in cross-coupling reactions of triethoxy(phenyl)silane with various aryl halides under microwave irradiation. This complex is an efficient and stable catalyst for the synthesis of substituted biphenyls that is non-sensitive to air and moisture. The combination of dimeric complex as homogenous catalyst, microwave irradiation, DMF as microwave-active polar solvent and TBAF as microwave-active additive led to excellent yields in short reaction times.
