An efficient protocol for the synthesis of a variety of azobenzenes and hydrazines from aromatic amines under mild reaction conditions is developed using Cu(I) catalyst. The copper cataylst used in this study comprises of CuBr, DMAP and AIBN. The plausible proposed mechanism for this dehydrogenative homo coupling of aromatic amines is depicted.

A copper-catalyzed N-N bond-forming reaction was performed by a dehydrogenative homocoupling of N-alkylanilines, affording N,N-dialkyl-N,N- diphenylhydrazines in 72-88% yields. This new strategy has the advantages of direct synthesis from N-alkylanilines,

A novel N-N coupling reaction was developed through the oxidation of rare-earth-metal-nitrogen bonds produced by treatment of the easily available rare-earth-metal amides [(Me3Si)2N]3RE(μ-Cl) Li(THF)3 with aromatic primary or secondary amines. The reaction provides the symmetrical or unsymmetrical azo compounds and hydrazine derivatives in good to high yields within a very short time under mild conditions.
