运用4-Benzylpyridine(4-BePy)作为轴向配体,通过Mn(TPP)Cl/NaOCl单加氧酶模拟体系可以使低碳烯烃丙烯十分有效地环氧化,环氧丙烷收率达80％,选择性近100％。对该催化反应的表观动力学行为作了较为细致的研究,并据此提出了丙烯环氧化的反应机制。该催化反应的速率控制步骤取决于底物丙烯的浓度,为简单烯烃通过Mn(TPP)Cl环氧化的第一个例子。 Using 4-Benzylpyridine (4-BePy) as an axial ligand, the light olefins propylene can be epoxidized very efficiently through a Mn (TPP) Cl / NaOCl monooxygenase simulation system with a propylene oxide yield of 80% , Nearly 100% selectivity. The apparent kinetic behavior of the catalytic reaction was studied in detail, and the reaction mechanism of propylene epoxidation was proposed. The rate control step of this catalytic reaction depends on the concentration of the substrate propylene, the first example for the epoxidation of simple olefins by Mn (TPP) Cl.
