[TPPFe]_2O催化空气直接氧化乙苯(英文)

Direct Oxidation of Phenylethane With Air Catalyzed by [TPPFe]_2O

在 [TPPFe]2 O催化下 ,空气能够直接氧化乙苯生成苯乙酮和α -苯乙醇 ,反应对α位的选择性高达 10 0 % .此外 ,反应温度和反应时间对反应的产率和选择性均有一定的影响 .随着反应时间的延长 ,总产率增加 ,苯乙酮的选择性略有增加 ,而α -苯乙醇的选择性相应降低 ;当反应温度升高时 ,总产率增加 ,苯乙酮的选择性略有下降 ,而α

Phenylethane was oxidized directly to hypnone and α-phenyethanol with air under the catalysis of μ-oxo-bis-iron porphyrin of products at alpha position is 100%.The reaction temperature and time have influences on the yield and the selectivity of products.With the reaction time extending,the yield of products increased,but the selectivity of hypnone slightly increased and the selectivity of α-phenyethanol slightly descended.With the temperature raising,the selectivity of hypnone descended and the selectivity of α-phenyethanol increased.
