摘要 合成了几种具六齿配位的8-羟基喹啉铁类配合物,考察了这些配合物在催化过氧化氢氧化环己烷的催化性能。结果表明,配体的卤素取代基对催化剂有稳定作用,能提高其催化活性。二卤代的催化剂具有稳定的六齿配位结构,其催化反应速率慢;采用混合配体配位的催化剂能够明显加快反应速率,提高催化活性。 8-quinoliolato Fe^Ⅲ complexes （ Q3Fe^Ⅲ） with hexadentate mode were synthesized and their catalytic behaviors were investigated for oxidation of cyclohexane with hydrogen peroxides. The results indicated that 5-chlorinated Q3 Fe^Ⅲ catalyst was unstable and exhibited low catalytic activity; 5- and 7-dihalogenated Q3Fe^Ⅲ catalysts exhibited stable and significantly-enhanced cyclohexane conversion. 5-chlorinated and 5, 7-di-chlorinated ligands co-coordinated Fe^Ⅲ catalyst were superior to single ligand coordinated Fe^Ⅲ catalysts both in reaction rate and catalytic activity, which might be due to the distorted hexadentate structure.
