烯烃的环氧化反应

并且，MMO是一种非专一性的、具有广泛应用前景的工业生物催化剂，能催化C1C20各种取代烃的羟基化反应与C2C10各种取代烯烃的环氧化反应。

Meanwhile , as a non-special biocatalyst , MMO can catalyze hydroxylation of all kinds of alkanes from Cj to € 20 and epoxidation of alkenes from € 2 to Qoas well .

但是传统方法合成的TS-1孔径较小，只能催化小分子烯烃的环氧化反应，限制了TS-1的应用范围。

However , TS-1 prepared with the traditional method can only catalyze the epoxidation of alkenes of small molecules due to its microporous structure and therefore limits its application .

到目前为止，很多的金属配合物已经被应用到烯烃的环氧化反应中。

Many Schiff base metal complexes have been applied in this process so far .

在催化领域，有机合成中非官能化烯烃的环氧化反应一直是化学工作者备受关注的研究热点。

Epoxidation of unfunctionalized olefins in organic synthesis has always attracted the interest of chemists in catalytic field .

多金属氧酸盐作为一类有效的催化剂被越来越多的应用于各种液相氧化反应，如：烯烃的环氧化反应、醇的氧化反应以及吡啶的氮氧化反应等等。

Polyoxometalates are used widely in the liquid oxidation reactions as the effective catalysts , such as olefin epoxidation , alcohol oxidation and pyridine oxidation .

所合成的非均相SalenMn（III）催化剂在非官能团化烯烃的不对称环氧化反应中表现出了高的催化活性和对映选择性。

The as-synthesized heterogeneous chiral salen Mn ( III ) catalysts were highly active and enantioselective in the asymmetric epoxidation of unfunctionalized olefins .

对于烯烃的不对称环氧化反应，存在着两个常见的催化体系：Sharpless体系和Jacobsen体系。前者适用于烯丙醇类烯烃的不对称环氧化反应；

There are two general systems for the enantioselective epoxidation of olefins : Sharpless catalytic system and Jacobsen system , effective for the epoxidation of allylic alcohols and nonfunctional alkenes , respectively .

烯烃的环氧化物是应用最广泛的有机中间体，在有机合成反应中烯烃的环氧化反应占有十分重要位置。

The epoxy compounds of olefins is an organic intermediates applied most extensively . Epoxidation of olefins is the most important reactions in organic synthesis .
