Application

4,4′-Di-tert-butyl-2,2′-dipyridyl can be used as a ligand:      
  • In the synthesis of oxidovanadium(IV) complex [VOCl2(dbbpy)(H2O)], which is used as a catalyst for the epoxidation of cyclooctene in the presence of tert-butyl hydroperoxide.     
  • In iron-catalyzed ortho-allylation of 1-arylpyrazoles via C-H activation.     
  • In iridium-catalyzed borylation of (hetero)arenes.      
  • In iron-catalyzed arylation of heterocycles in the presence of metallic Mg.      
  • In nickel-catalyzed decarboxylation of block copolymers.
