A mild, transition metal-free, and environmentally benign NBS-promoted C–N bond formation of N-heterocycles is successfully demonstrated. A series of heterocyclic derivatives are readily prepared under mild conditions in moderate to good yields.
成功证明了温和,无过渡金属且对环境无害的NBS促进的N杂环C–N键的形成。在温和条件下容易以中等到良好的产率制备一系列杂环衍生物。
