Phenylselenoetherification and phenylselenolactonization were performed in one step by electrolysis of unsaturated alcohols or carboxylic acids and diphenyl diselenide in organic solvent containing halide ions as mediators.

Time-economical synthesis of selenofunctionalized heterocycles <i>via</i> I<sub>2</sub>O<sub>5</sub>-mediated selenylative heterocyclization
A time-economical and robust synthesis of various selenofunctionalized heterocycles was accomplished via I2O5-mediated selenocyclizations of olefins with diselenides. Using this method, 116 selenomethyl-substituted heterocycles were synthesized with up to 97% isolated yield in minutes. Additional features of this new protocol include the use of an inorganic oxidant, mild conditions, and easy operation
通过I 2 O 5介导的烯烃与二硒化物的硒环化,实现了各种硒官能化杂环的经济且稳健的合成。使用这种方法,在几分钟内合成了 116 个硒甲基取代的杂环,分离产率高达 97%。这个新协议的其他特点包括使用无机氧化剂、温和的条件和易于操作。初步研究表明,这种转化是通过硒基碘诱导的亲电环化进行的。
