Abstract

Brand2 and coworkers found the--SCH3 group to be strongly bathochromic as compared with-OCH3 when introduced into azobenzene or into triphenyl carbinol, but they did not prepare any real dyes except to tetrazotize the dimethylether of o, o'-dimercapto-benzidine and couple it with salicylic acid, which gave a direct yellow on cotton, and with H-acid which gave a blue shade.
