reaction of alkyl halides with lanthanum metal have been shown. The reduction of alkyl iodide with 1/3 equiv of lanthanum metal efficiently proceeded to give the corresponding reductive dimerized products along with the formation of reduction and dehydroiodination products. In the case of alkyl bromides and chlorides, the reaction did not proceed under the same reaction conditions as that of alkyl iodides;
已经显示出卤代烷与镧金属反应的结果。用1/3当量的镧金属有效地进行烷基碘的还原,得到相应的还原二聚产物,同时形成还原和脱氢碘化产物。在烷基溴和氯化物的情况下,反应没有在与烷基碘相同的反应条件下进行。但是,通过加入催化量的碘可以大大促进该反应。建议包括烷基的反应途径。
