建立了一种新的无金属催化剂催化非活性烯烃与简单羧酸的氧化偶联反应。该方法是基于二硒烷和光氧化还原催化剂的协同相互作用，其允许使用环境空气或纯O2作为终端氧化剂。在此条件下，一系列官能化和非官能化烯烃都可以很容易地转化为相应的烯丙基酯产物，产率高达89%，具有良好的区域选择性和良好的官能团耐受性。
A new metal-free catalysis protocol for the oxidative coupling of nonactivated alkenes with simple carboxylic acids has been established. This method is predicated on the cooperative interaction of a diselane and a photoredox catalyst, which allows for the use of ambient air or pure O2 as the terminal oxidant. Under the title conditions, a range of both functionalized and nonfunctionalized alkenes can be readily converted into the corresponding allylic ester products with good yields (up to 89%) and excellent regioselectivity as well as good functional group tolerance.
