摘要
本文首次报道了μ-氧代双卟啉锰(Ⅲ)系列化合物对PhIO温和氧化环己烷反应的催化作用.与目前文献报道的其它类型卟啉相比,这些卟啉对环己烷单充氧反应具有更好的催化性能.动力学研究表明,卟啉环上取代基的特性常数与它们催化下的环己烷烃基化反应速率常数之间存在Hammett关系.
This paper first reported the catalysis for cyclohexane monooxygenation with PhIO at room temperature and in air atmosphere by μ-oxo-bisporphinatomanganese ( Ⅲ ) compounds. Compared with other metalloporphyrins reported so far, μ-oxo-bisporphinatomanganese ( Ⅲ) showed the better catalytic properties on cyclohexane hydroxylation. The kinetic researches found that there existed Hammett relationship between the substituents on porphyrin rings and the rate constants of the reactions catalyzed by μ-oxo-bisporphinatomanganese (Ⅲ).
