In chapter three, the activating agents of ytterbium have been examined. Barbier-type reaction promoted by ytterbium metal was examined. The experimental results shown that the yield of Barbier reaction of imines with allylic bromide promoted by ytterbium is higher than that of aldehydes and ketones with allylic bromide under the same reaction conditions. In this chapter, the reductive cleavage of Se-Se and S-S bond induced by ytterbium metal was also studied.

首先研究了金属镱的活化剂以及活化方法，接着考察了金属镱促进的Barbier反应及其在合成高烯丙基胺和高烯丙基醇中的应用，以及影响该反应的主要因素；究了金属镱促进的二硫醚和二硒醚的S—S键和Se—Se键的还原断裂，继而与氯代烃，胺基甲酰氯反应生成相应的硫醚，硒醚，胺基甲酸硫代酯和硒代酯。
