✦ Synopsis

Photochemical reactions of some haloheterocycles bearing electron-withdrawing groups 1a-d with electron-poor olefins 2a-c gave the addition products 3a-f and 3h-m in good yields. Other products obtained were the corresponding olefins 4a-k and the alkanes 3g. These reactions involve homolytic cleavage of the carbon-halogen bond to give the corres-
