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.

Treatment of IrCl(3)x H(2)O with one equivalent of 4,4'-di-tert-butyl-2,2'-bipyridyl (dtbpy) in N,N-dimethylformamide (dmf) afforded [IrCl(3)(dmf)(dtbpy)] (1). Alkylation of 1 with Me(3)SiCH(2)MgCl resulted in C--Si cleavage of the Me(3)SiCH(2) group and formation of the Ir(III) silyl dialkyl compound [Ir(CH(2)SiMe(3))(dtbpy)(Me)(SiMe(3))] (2), which
