| titleOfInvention | Sulphonylamidrazone prepn - single stage process using oxidation agents |
| abstract | Sulphonylamidrazones are prepd. by reaction of amidrazones in a single stage with sulphinic acids in the presence of oxidation agents e.g. K persulphate, K hexacyanoferrate (111), KMnO4 or K bichromate. The prodts. are of formula: (where R1 = aryl; R2 = alkyl; R3 = alkyl; R4 = alkyl or aryl; or R1 and R2 together represent a gp. necessary for completion of a 5 or 6-membered hetero ring or R2 and R3 together represent a gp. necessary for completion of a 5-, 6- or 7-membered hetero ring). The prodts. are intermediates in the synthesis of azo dyes - can be used in colour photography. |
