二叔丁基二氮杂环丙酮-Cu催化的烯烃氧化成酮的研究

1,2-Di-tert-butyldiaziridinone-Cu Catalyzed Oxidation of Alkenes to Ketones

以二氯甲烷为溶剂,1,2-二叔丁基二氮杂环丙酮为配体,溴化亚铜作催化剂,过氧化叔丁醇为氧化剂,催化氧化偕二取代烯烃氧化成酮,获得较好的产率(up to 91%).该反应具有操作简单、催化剂用量少、选择性高等优点,为芳香端烯的断键氧化提供了好的方法.

Oxidation of 1,1-disubstituted alkenes to ketones in the complex of CuBr and 1,2-di-tert-butyldiaziridinone in CH2Cl2 was researched. The reaction offered high yields （up to 91%） with low catalyst loading and mild conditions. The method provided a good choice for the oxidative cleavage of terminal olefins to ketones.
