was substantially more reactive than the other three isomers, which had approximately equivalent reactivities. /sup 1/H NMR spectra were used to confirm structures of all compounds, and typical antimigrations were observed. Mixture compositions matched those anticipated from relative reactivities. Irradiations of the methanesulfonates were conducted in acetic acid-acetonitrile with 300-nm light. Of
