| Abstract | ||
| The synthesis of azo compounds (9-11) has been achieved by reaction of diazonium salts of substituted 4`-aminosulfonanilides with some aromatic amines or phenols 4-Nitroaniline (1) is served as a synthon for 2,6-dibromo-4-nitroaniline (6). The compounds (1 and 6) undergo sulfonylation with methane- and 4-toluene sulfonyl chloride to give the corresponding sulfonanilides (2, 3, 7). The nitro group in these compounds is reduced to amino group to produce compounds (4, 5, 8). These compounds are diazotised to the corresponding diazonium salts, which are coupled with different aromatic amines or phenols to produce the azo compounds (9-11). The structure of the synthesized compounds has been confirmed on the basis of physical and spectral measurements | ||
