Direct C(sp3)-H functionalization of alkyl nitriles is a low toxic and facile route to nitrile-containing compounds. In this research, the Ag2CO3-mediated nitrile methylenation of enol acetates is developed to prepare γ-ketonitriles through the direct C(sp3)-H oxidative functionalization of acetonitrile. A radical pathway is proposed, and acetonitrile serves both as solvent and CN-containing radical
烷基腈的直接C(sp3)-H官能化是向含腈化合物的低毒易制毒途径。在这项研究中,开发了通过乙腈的直接C(sp 3)-H氧化功能化,由Ag 2 CO 3介导的烯醇乙酸盐腈腈甲基化反应,以制备γ-酮腈。提出了一种自由基途径,乙腈既是溶剂又是含CN的自由基源。
