Abstract

The Claisen rearrangement is a [3,3]-sigmatropic rearrangement which is an important method for new C-C bond formation in organic synthesis. This reaction is a typical thermal reaction that requires a high temperature and long reaction time. In this paper, the acceleration effects of the iron (III) chloride (FeCl3) catalyst and microwave irradiation during the Claisen rearrangement reaction of allyloxyarene derivatives are reported. The FeCl3 catalyst was able to initiate the reaction at low temperature and induced the subsequent cyclization reaction. The moderation of excellent yields was obtained in a short reaction time. The formation of complex ferric-arenes under microwave irradiation conditions to efficiently absorb the microwaves was expected and confirmed.
微波条件下氯化铁催化烯丙氧芳烃克里森重排反应
Claisen重排是一种[3,3]-符号位重排,是有机合成中形成新碳-碳键的重要方法。该反应为典型的热反应,需要较高的温度和较长的反应时间。本文报道了氯化铁(FeCl3)催化剂和微波辐照对烯丙氧芳烃衍生物Claisen重排反应的加速作用。FeCl3催化剂能在低温下引发反应并诱导随后的环化反应。在较短的反应时间内获得了优异的产率。预期并证实了在微波辐照条件下,铁-芳烃络合物的形成能够有效地吸收微波。
