| titleOfInvention | Process for the production of 2-aryl-2H-1,2,3-triazoles |
| abstract | 4-Akylthiomethyl-2-aryl-2H-1,2,3-triazoles and 4-arylthiomethyl-2-aryl-2H-1,2,3-triazoles are produced from γ-chloroacetoacetyl chloride, aryldiazonium salts and thiolates. In a first step, the aryldiazonium salt is reacted with the chloroacetoacetyl chloride to the corresponding 3-chloropyruvaldehyde-arylhydrazone, which is converted with the thiolate into the corresponding 3-alkylthio or 3-arylthiopyruvaldehyde-arylhydrazone. The 3-alkylthio or 3-arylthiopyruvaldehyde-arylhydrazone is cyclized with hydroxylamine-O-sulfonic acid to the desired 2-aryl-2H-1,2,3-triazole. |
