Two preparatively attractive methods for the azidation of alkyl radicals are described. Secondary and tertiary alkyl iodides and dithiocarbonates are easily converted into the corresponding azides, either by reaction with ethanesulfonyl azide in the presence of dilauroyl peroxide, or by treatment with benzenesulfonyl azide and hexabutylditin in the presence of a radical initiator. Interestingly, intramolecular
描述了用于烷基基团叠氮化的两种制备性有吸引力的方法。通过在过氧化二月桂酰存在下与乙磺酰叠氮化物反应,或在自由基引发剂存在下用苯磺酰叠氮化物和六丁基二锡处理,仲和叔烷基碘和二硫代碳酸酯很容易转化为相应的叠氮化物。有趣的是,分子内串联自由基环化-叠氮化过程可以以高产率进行。
