摘　　要：以常见的二氧六环为溶剂体系,在可见光的照射下,1-芳基环烯烃在光催化剂Eosin Y的催化下,经过选择性的烯丙位C-H键活化反应制备出一系列β-芳基烯酮产物.该反应是经过了原位生成二氧六环过氧化物活性中间产物的选择性攫氢作用,接着再发生氧气捕获以及脱水反应,最终实现1-芳基环烯烃到β-芳基烯酮的转化.Under the irradiation of visible light,a series ofβ-aryl kenone products were prepared from 1-aryl cycloal kenes via a selective allylic C-H bond activation reaction by the photocatalyst Eosin Y in a common dioxane solvent.The conversion of 1-aryl cycloal kenes toβ-aryl kenones was achieved by selective hydrogen abstraction from the in-situgeneration of the active intermediate of dioxane peroxide,followed by oxygen capture and dehydration.
