| Abstract：2 Nitrobenzyl alcohols were oxidized to 2 nitrobenzaldehydes via copper catalyzed air oxidation. This represents a new and facile route to the nitrobenzaldehydes. Optimum reaction conditions were as follow: the oxidition molar ratio of nitrobenzaldechol∶CuCl∶DEAD∶o phenanthroline∶K 2CO 3 was 1∶0.05∶0.05∶2, reaction temperature 78～82℃, reaction time 3 h. The overall yield of 2 nitrobenzaldehyde was 74.1%. And the catalyst can be recycled. |
| Key words：2 Nirobenzyl alcohols; catalysis; oxidation; 2 nitrobenzaldehyde |
