| Abstract: | 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. |
