铁配合物催化作用下分子氧对环己烯的氧化

Oxidation of Cyclohexene Catalyzed by Iron(Ⅱ,Ⅲ)1,10-Phenanthroline and 2,2′-Bipyridine Complexes

在铁(Ⅱ,Ⅲ)-2,2′-联吡啶和铁(Ⅱ,Ⅲ)邻菲啰啉配合物的催化作用下,常压、70℃时用氧气或空气氧化环己烯,得到环己烯-2-醇-1和环己烯-2-酮-1,反应3.5h。转化率可达36.46%,酮、醇在产物中的总选择性大于91.40%.探讨了环己烯与催化剂摩尔比、温度及添加剂对催化活性的影响.

Oxidation of cyclohexene affords corresponding ketone and alcohol at 70℃ under 1 atm of O_2 or air without any solvent or coreductant catalyzed by iron(Ⅱ,Ⅲ)-bipy ridine and iron(Ⅱ,Ⅲ)-phenoanthroline complexes with the conversion of 10%～36% and the se- lectivity to total cyclohexenyl-ketone and alcohol of 91%～98%.The influence of tempera- ture and substrate/cat.(mol/mol)to the catalytic activity and selectivity are discussed.
