variety of nucleophiles. The homolytic scission of diselenides under visible-light conditions coupled with the aerobic selenol oxidation to diselenides allowed the successful implementation of three-component selenofunctionalization under visible-light irradiation in open-air conditions. The mechanistic studies revealed the critical role of oxygen content in a reaction medium, where the electron transfer
已经使用多种亲核试剂开发了无光催化剂的可见光诱导的烯烃硒功能化。二硒化物在可见光条件下的均裂与硒醇有氧氧化成二硒化物相结合,使得在露天条件下可见光照射下的三组分硒功能化得以成功实施。机理研究揭示了氧含量在反应介质中的关键作用,其中控制了从碳基自由基到分子氧或硒基自由基的电子转移过程。
