The cooperative interaction of a diselane and a photoredox catalyst enables a metal-free protocol for the oxidative coupling of nonactivated alkenes with simple carboxylic acids in ambient air or pure O2 as the terminal oxidant. A range of both functionalized and nonfunctionalized alkenes can be readily converted into the corresponding allylic ester with good yields and excellent regioselectivity as well as good functional group tolerance.
