An efficient and broadly applicable process is reported for the direct alkylation of C-H bonds in heteroarenes, privileged scaffolds in many areas of science. This reaction is based on the copper-catalyzed addition of alkyl radicals generated from activated secondary and tertiary alkyl bromides to a wide range of arenes, including furans, thiophenes, pyrroles, and their benzo-fused derivatives, as well as coumarins and quinolinones.
报道了一种高效且广泛适用的方法,用于杂芳烃中C-H键的直接烷基化,杂芳烃是许多科学领域中重要的骨架结构。该反应基于铜催化的活性仲烷基和叔烷基溴生成的烷基自由基与多种芳烃的加成反应,这些芳烃包括呋喃、噻吩、吡咯及其苯并稠合衍生物,以及香豆素和喹啉酮。
