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.
cis-α,α'-二甲基芪 (1) 的敏化光氧化取决于敏化剂、溶剂和温度。在室温下,1 的 Ru(bpy)32+- 或 TPP-敏化光氧化反应提供二氧杂环丁烷氢过氧化物 (2),而当使用 RB 或 MB 作为敏化剂时,仅获得烯丙基氢过氧化物 (3)。在低温下,2 的形成与所使用的敏化剂无关。
