摘要 以氯胺-B为氧化剂,KI或NaBr为卤源,实现了末端炔烃的直接氧化卤化。该反应能够在温和的反应条件下以良好至优异的产率普遍且实用地获得具有合成价值的1-溴炔和1-碘炔。
Abstract A direct oxidative halogenation of terminal alkynes has been realized using chloramine-B as the oxidant and KI or NaBr as the halogen source. This reaction enables a general and practical access to synthetically valuable 1-bromoalkynes and 1-iodoalkynes in good to excellent yields under mild reaction conditions.
