Herein, we report peroxidative dearomatization of 2-naphthol and C−H peroxidation of 3-arylbenzofuran-2-ones with 66–94% yield under catalyst-free conditions using continuous flow module. Besides, an approach for the synthesis of N-substituted-2-phenylbenzo[d][1,3]dioxole-2-carboxamide has been achieved via the skeletal rearrangement of peroxybenzofuranone using amines in the absence of catalyst under
在此,我们报道了使用连续流模块在无催化剂条件下进行 2-萘酚的过氧化脱芳构化和 3-芳基苯并呋喃-2-酮的 C−H 过氧化,产率达 66-94%。此外,在连续流动下,通过过氧苯并呋喃酮的骨架重排,在没有催化剂的情况下,实现了合成N-取代-2-苯基苯并[ d ][ 1,3 ]二氧杂环戊烯-2-甲酰胺的方法。机理研究表明,这种过氧化反应是在热解条件下通过自由基形成进行的。
