Abstract: The photobehavior of the acyclic vinyl iodide 2, the I-iodocycloalkenes 11-14 and 39, the (ha1omethylene) cycloalkanes 45-48, and the (dihalomethy1ene) cyclohexanes 62- 64 has been studied. Except for the dichloride 64, which exhibited only radical behavior, each of the halides afforded a mixture of ionic and radical products. The two bromides studied, 48 and 63, afforded lower ratios of ionic to radical products than the ...
