摘要
在本文中，我们报道了在温和的反应条件下，使用稀过氧化氢作为氧化剂，在TS-1上进行了高效的区域选择性环化。在Al- ti - beta和Al- ti - mcm -41上的芳樟醇氧化中观察到类似类型的氧化环化(双功能行为，环氧化之后是酸催化环化)，其中Al位点的酸度是导致环化的原因。
Highly efficient and regioselective cyclization catalyzed by TS-1
In this paper we report a highly efficient regioselective cyclization of such olefinic alcohols over TS-1, under mild reaction conditions using dilute hydrogen peroxide as oxidant. Similar types of oxidative cyclization (bifunctional behavior, epoxidation followed by acid catalyzed cyclization) was observed in the oxidation of linalool over Al-Ti-Beta and Al-Ti-MCM-41 where the acidity at the Al sites was responsible for the cyclization.
