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.

The rate of bromination of azobenzene by acidified hypobromousacid has been measured and compared with those of benzene, toluene, and bromobenzene under the same conditions.Determination of o/m/p ratios for attack on azobenzene show that the rate of attack at the meta position is much lower than expected on the basis of the Hammett ?m value for the phenylazo substituent.Abnormally low amounts of meta isomer were also observed for the case of bromobenzene, but not toulene.The rates of bromination of two monosubstituted azobenzenes (m-Br, and p-F) were alsodetermined and comparedwith that of azobenzene.
