Abstract
Symmetrical azo compounds were synthesized from primary aromatic amines using n-BuMgBr as a base, oxygen as an oxidant, and CuCl2 as a catalyst.
Notes
a Reaction conditions: Aniline (1 mmol) was added to a solution of a base in THF (8 mL). After stirring for 1/2 h, an oxidant was added to the reaction mixture, which was stirred at room temperature for the specified time.
