The first example of a hypervalent iodine(III)‐mediated oxidative fluorination of alkylsilanes by fluoride ions without the use of transition metals is demonstrated. This reaction is operationally simple, scalable, and proceeds under mild reaction conditions. Mechanistic studies suggest the involvement of a single‐electron transfer resulting from the interaction of an organopentafluorosilicate and
在不使用过渡金属的情况下,通过氟离子对烷基硅烷进行高价碘(III)介导的氧化氟化的第一个例子得到了证明。该反应操作简单,可扩展,并且在温和的反应条件下进行。机理研究表明,由于五氟有机硅和二氟化芳基碘鎓的相互作用而引起的单电子转移,这是在氟离子存在下分别由相应的烷基硅烷和碘代苯就地产生的。
