The aerobic dehydrogenative cyclization of alkenes with easily accessible diselenides facilitated by visible light is reported. Notably, the features of this transition-metal-free protocol are pronounced efficiency and practicality, good functional group tolerance, atom economy, and high sustainability, since ambient air and visible light are adequate for the clean construction of five- and six membered heterocycles in yields of up to 98%.
报告了可见光促进的烯烃与易得二硒醚的有氧脱氢环化反应。值得注意的是，该无金属过渡方案的特点是效率高、实用性强、官能团耐受性好、原子经济性高、可持续性好，因为环境空气和可见光足以在高达 98%的收率下清洁构建五元和六元杂环。
