number of γ-cyanoalkyl radicals were generated by sustainable N-heterocyclic carbene catalysis in tin-, transition-meal-, and light-free conditions, followed by insertion into biaryl isonitriles, thus leading to the rapid assembly of a variety of diversely functionalized 6-cyanoalkyl phenanthridines. A preliminary mechanism study revealed that a single-electron transfer radical process was possibly involved
在无锡、过渡餐和无光条件下,通过可持续的 N-杂环卡宾催化产生了许多 γ-氰基烷基自由基,然后插入到联芳基异腈中,从而导致各种不同功能化的快速组装6-氰基烷基菲啶。初步的机理研究表明,可能涉及单电子转移自由基过程。
