ium by reaction of bis(trimethyltin)dichloromethane with n-butyllithium, of trimethyltinbromochloromethyllithium by reaction of bis(trimethyltin)bromochloromethane with n-butyllithium and of trimethyltindibromomethyllithium by reaction of trimethyl(tribromomethyl)tin or bis(trimethyltin)dibromomethane with n-butyllithium is described. All of these new lithium reagents are stable in THF-rich media only
通过双(三甲基锡)二氯甲烷与正丁基锂反应制备三甲基锡二氯甲基锂,通过双(三甲基锡)溴氯甲烷与正丁基锂反应制备三甲基锡溴氯甲基锂,通过三甲基(三溴甲基)锡或双(三甲基锡)二溴甲烷反应制备三甲基锡二溴甲基锂。描述了丁基丁基锂。所有这些新的锂试剂仅在低温(-95°或更低)下才在富含THF的介质中稳定。它们与三甲基氯硅烷的反应由于以下事实而变得复杂:在如此低的温度下,产物三甲基甲硅烷基(三甲基锡)二卤甲烷与锂试剂的反应性与三甲基氯硅烷相当。其他淬灭剂(如甲基碘)也会发生类似的并发症。
