| titleOfInvention | Aromatic sulfonamide sulfonyl chloride compounds |
| abstract | An aromatic sulfonamide sulfonyl chloride, useful as an intermediate in the preparation of cyan dye-releasing redox compounds for diffusion transfer photographic materials, represented by the following general formula (I) <IMAGE> (I) wherein A represents a divalent benzene nucleus or a divalent naphthalene nucleus, in which in each nucleus the bonding thereto is symmetrical, and a method for the synthesis thereof comprising reacting an aromatic disulfonyl chloride represented by the formula (IIa) or (IIb) <IMAGE> (IIa) <IMAGE> (IIb) wherein the two sulfonyl chloride groups are substituted at symmetrical positions on the benzene and the naphthylene ring, with 5-amino-1-naphthol. |
