A novel and facile visible-light-mediated alkylation of indoles and nitroalkenes has been developed. In this protocol, rose bengal acts as a photosensitizer, and environmentally benign water was used as the green and efficient reaction medium. Indoles reacted smoothly with nitroalkenes under the irradiation of visible-light and generated corresponding 3-(2-nitroalkyl)indoles in moderate to good yields (up to 87%).
已开发出一种新颖且简便的可见光介导的吲哚与硝基烯烃的烷基化反应。在该反应体系中，孟加拉玫瑰红作为光敏剂，环境友好的水被用作绿色高效的反应介质。吲哚在可见光照射下与硝基烯烃顺利反应，以中等至良好的产率（高达87%）生成相应的3-(2-硝基烷基)吲哚。
