Abstract:
In this paper, reporter introduced some achievement in nit rat ing arene w ith ozone mediated. Experiments show that the reacting ability w as related to ionizing potent ials of arene, ρ+ ( - 6.8) and isomer distribut ion in the reaction was equal to that of conventional method. Reporter suggested that the react ion process be CT process, by comparison and ex per-i ment . The CT- Complexis is decomposed into nit roaromat ics f inally.
