Method for producing 2-phenylbenzotriazoles |
| abstract |
PROBLEM TO BE SOLVED: To provide a novel method for producing 2-phenylbenzotriazole which performs a reduction reaction with hydrogen under acidic conditions, and to perform an inexpensive and clean reduction reaction with hydrogen in the presence of an acidic substance. With almost no side reactions or dechlorination, It is easy to separate and purify 2-phenylbenzotriazole, which is the target product, and to obtain a novel 2-phenylbenzotriazole with high yield and productivity. The provision of a process for the preparation of phenylbenzotriazole. SOLUTION: General formula II Wherein 2-phenylbenzotriazole-N-oxides represented by are reduced with hydrogen in an acidic condition in at least one solvent selected from the group consisting of water and an organic solvent in the presence of a hydrogenation catalyst. The general formula I A method for producing 2-phenylbenzotriazoles represented by the formula: |
