A Mn‐electrocatalytic ring‐opening azidation of tert‐cyclobutanols has been developed. The regioselective method is applicable for the azidation of a diverse array of cyclobutanols to provide γ‐azido ketones in 23‐91% yields under chemical oxidants‐free reaction conditions. Detailed mechanistic studies suggest the process of Mn‐mediated alkoxy radical generation followed by β‐scission to form carbon‐centered radical species is possibly involved in this transformation.

锰介导的环丁醇衍生物与 TMSN3 的电氧化开环叠氮化反应

已开发出叔环丁醇的锰电催化开环叠氮化反应。该区域选择性方法适用于多种环丁醇的叠氮化，在无化学氧化剂的反应条件下以 23-91% 的产率提供 γ-叠氮酮。详细的机理研究表明，Mn介导的烷氧基自由基生成，随后β-断裂形成以碳为中心的自由基物质的过程可能参与了这种转变。
