Application of 15862-18-7, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.15862-18-7, Name is 5,5′-Dibromo-2,2′-bipyridine, molecular formula is C10H6Br2N2. In a Article，once mentioned of 15862-18-7
A novel class of tetrathiolated aryleneethynylene oligomers was obtained by the Cassar-Heck-Sonogashira coupling between S,S-(5-ethynyl-1,3-phenylene) bis(methylene)diethanethioate (1) and aryl diiodides or dibromides. Although standard coupling conditions are effective in the case of iodo derivatives, the addition of free triphenylphosphane to the reaction mixture was required to overcome the slower reaction rate of dibromoarenes. Oligomers with an extended conjugated system could be obtained starting from a higher homologue of 1 by applying the same synthetic approach. These oligomers represent interesting molecular wires, potentially able to self-assemble on various substrates, including gold and other noble metals in the form of thin films or nanoparticles. The chelating arrangement of the thiol functionalities should ensure stable anchoring and would also represent an interesting novel feature in the study of single molecule conduction with respect to traditional monodentate systems. A novel class of tetrathiolated aryleneethynylene oligomers was obtained bythe Cassar-Heck-Sonogashira coupling ofS,S-(5-ethynyl-1,3-phenylene) bis(methylene)diethanethioate with aromatic halides (bromides and iodides).
