The reactions of YbCl₂, SmCl₂, NdCl₂ with C₈H₈ have been studied.It is found that SmCl₂, NdCl₂ can react with C₈H₈ in THF at room temperature directly, forming SmCl₃(Sm(C₈H₈) Cl·2THF); NdCl₃, and (Nd(C₈H₈)Cl·2THF) respectively, which were characterized by elemental analysis and IR spectra.However, YbCl₂ does not react with C₈H₈ under the same conditions.The mechanism of the reaction is proposed: 2RECl₂+C₈H₈???19880414???(Cl₂REC₈H₈RECl₂)→RECl₃+REC₈H₈Cl The reactive activities of LnCl₂ in the reaction were found to be in the order: NdCl₂>SmCl₂>>YbCl₂., The reactions of YbCl₂, SmCl₂, NdCl₂ with C₈H₈ have been studied.It is found that SmCl₂, NdCl₂ can react with C₈H₈ in THF at room temperature directly, forming SmCl₃(Sm(C₈H₈) Cl·2THF); NdCl₃, and (Nd(C₈H₈)Cl·2THF) respectively, which were characterized by elemental analysis and IR spectra.However, YbCl₂ does not react with C₈H₈ under the same conditions.The mechanism of the reaction is proposed: 2RECl₂+C₈H₈(Cl₂REC₈H₈RECl₂)→RECl₃+REC₈H₈Cl The reactive activities of LnCl₂ in the reaction were found to be in the order: NdCl₂>SmCl₂>>YbCl₂.
