Sensitized photooxidation of cis-α,α'-dimethylstilbene(1) depends on sensitizer, solvent, and temperature.At room temperature, Ru(bpy)3²⁺- or TPP- sensitized photooxidation reaction of 1 affords a dioxetane hydroperoxide(2), while only an allylic hydroperoxide(3) is obtained when RB or MB is used as sensitizer.At low temperature, 2 comes to be formed independent of the sensitizer used.
