    • Abstract

       

      The new acrylic acid derivatives diethyl 2-(2,2' -bipyridin-4-ylmethylene)malonate and diethyl 3,3' -(2,2' -bipyridine-4,4' -diyl)diacrylate which may be used for the introduction of metal coordination sites in polyacrylates were synthesized and characterized. Intermediates of the syntheses were prepared by improved synthetic protocols working under microwave conditions whenever it was advantageous for the resulting productin terms of reaction time and/or chemical yield. In addition, the crystal structure of one of the intermediates, 4,4' -dibromo-2,2'-bipyridine (6), is reported, in which molecules are arranged into infinite chains by C-H—Br interactions.
