Site-selective arylation of commercially available 2,3,5,6-tetrachloropyridine has been accomplished, using the Suzuki-Miyaura reaction. The reaction conditions were thoroughly optimized, allowing the selective synthesis of mono-, di-, tri- and tetraarylated pyridines in good to quantitative yields. In addition, we studied the electrochemical properties of selected tetraarylpyridines by DPV-measurements. (C) 2015 Elsevier Ltd. All rights reserved.
