Two unusual examples of enone/alkene photocycloaddition involving a rearrangement of the intermediate 1,4-biradical are presented. The first reaction proceeds via the addition of one of the radical centers to a carbonyl C atom and subsequent bond cleavage, i.e., with rearrangement to a 1,3-biradical, while the second reaction involves abstraction of an H atom by one of the radical centers.
