oxidative difunctionalization of aryl alkynoates at room temperature to access stereodefined fully substituted α,β-unsaturated acids bearing a chalcogen functionality in high yields (up to 95%). The protocol is operationally simple, metal-free, scalable, and suppresses the usual CO2 exclusion phenomenon. The utility of this method was showcased in the synthesis of vinyl halides, vinyl selenides, and
已经设计了基于自由基的级联反应,用于在室温下烷基芳基酸酯的氧化双官能化,以高收率(高达95%)获得带有硫属元素官能团的立体定义的完全取代的α,β-不饱和酸。该协议操作简单,无金属,可扩展,并且抑制了通常的CO 2排除现象。该方法的实用性在卤化乙烯,硒化乙烯和3,3-二取代的茚满酮的合成中得到了展示。
