Per(2-thienyl)pyridines: Synthesis and Properties

Abstract

Starting from an easily available pyridinol derivative, a route to penta(2-thienyl)pyridine and related symmetrical compounds is reported. Key reactions are activation of the pyridine core and metal-catalyzed couplings proving the efficacy of these methods even in sterically highly encumbered systems. UV/vis and fluorescence spectra as well as first cyclovoltametric measurements of the synthesized novel thiophene–pyridine conjugates are reported
