2-Alkoxy-5-aminobenzene Sulfonates and 5-Diazo Derivatives thereof |
| abstract |
2-Alkoxyalkoxy-5-nitrobenzene sulfonates are of the general formula <IMAGE> where R<1> is an alkylene group of 2 or more carbon atoms, and R<2> is an optionally substituted alkyl group; preferably R<1> and R<2> have not more than 8 carbon atoms. Synthesis is by reduction of the sodium salt of the corresponding 5- nitro compound, preferably with iron dust, to give the sodium salt of the compound. The compound (I) can be diazotised with sodium nitrite and sodium hydroxide. The resultant diazonium salt can be reacted with a photographic colour coupler to make a dye-releasing redox compound. |
