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.

Packaging:

5, 25 g in glass bottle
