efficient strategy for cross coupling and multifunctionalization reaction of olefins via alkyl radicals. Herein, we demonstrate that isonitriles can serve as radical acceptors, which engage in a further radical cascade cyclization to furnish phenanthridine derivatives. We have also extended this photocatalytic process to cascade methylation reaction in one-pot with TMSCH2I as the radical precursor. Further
钯催化的光化学已被证明是一种通过烷基自由基进行烯烃交叉偶联和多功能化反应的有效策略。在这里,我们证明异腈可以作为自由基受体,参与进一步的自由基级联环化以提供菲啶衍生物。我们还将这种光催化过程扩展到以 TMSCH 2 I 作为自由基前体的一锅法级联甲基化反应。进一步的实验和计算研究表明,获得烷基自由基的分子内单电子转移过程参与了这种转变。
Electro‐oxidative Methylation of 2‐Isocyanobiaryls Using N,N‐dimethylformamide (DMF) as Carbon Source: Synthesis of 6‐Methylphenanthridines
This study reported the synthesis of 6-methylphenanthridines from 2-isocyanobiaryls using dimethylformamide (DMF) as a methyl carbon souce. The reactions were conducted in open-air atmosphere using electrochemical process at ambient temperature.
