The scientific interest in catalytic hydroaminoalkylation reactions of alkenes has vastly increased over the past decade, but these reactions have struggled to become a viable option for general laboratory or industrial use because of reaction times of several days. The titanium-based catalytic system introduced in this work not only reduces the reaction time by several orders of magnitude, into the
在过去的十年中,人们对烯烃催化加氢氨基烷基化反应的科学兴趣大大增加,但由于反应时间长达数天,这些反应一直难以成为一般实验室或工业用途的可行选择。这项工作中引入的钛基催化系统不仅将反应时间缩短了几个数量级,达到几分钟的范围,而且该催化剂也被证明可以很容易地从普通起始材料中获得,成本约为 1 欧元每毫摩尔催化剂。我们还能够正式对甲胺进行 CH 活化,并通过胺的甲硅烷基保护和简单的水脱保护实现与多种烯烃的偶联。
