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.

2,2′-Dihydroxyazobenzene (DAB), 2,2′-azotoluene (AT) and azobenzene (AB) were isolated in argon and xenon matrices and their molecular structures and photochemical transformations were characterized by infrared spectroscopy and theoretical calculations. A
Sterically Hindered Azobenzenes: Isolation of Cis Isomers and Kinetics of Thermal Cis --> Trans Isomerization

A series of highly hindered ortho-alkylated azobenzenes has been isolated in the cis configuration for the first time.The crystal structure of one of these compounds, cis-2,2',6,6'-tetraisopropylazobenzene, shows that the molecule accommodates the bulky s
OXIDATION OF AROMATIC AMINES WITH CHROMYL CHLORIDE - I OXYDATION OF AROMATIC PRIMARY AMINES

The oxidation of aromatic primary amines with chromyl chloride in carbon tetrachloride or chloroform, results in the formation of intermediate solid adducts (Etard adducts) which, on hydrolysis, give azobenzenes(1), 1,4-benzoquinones(2), anilino-1,4-benzoquinones(3), 1,4-benzoquinone anils(4) and anilino-1,4-benzoquinone anils(5) in yields which depend on the position, nature and degree of substitution of the ring.
