Fund Project: This project was supported by Laboratory of Rare Earth Chemietry and Physics, Changchun Institute of Applied Chemistry, Academy of Sciences, Laboratory of Qrganometallic Chemistry, Shanghai Institute of Organic Chemistry,Academy of Sciences and Chinese Natural Science Foundation, and A Key Research Project from State Science and Technology Commission.

Lanthanocene complexes Cp'₂LnCl(Cp'=Bu^tCp, Ln=Yb, Er;Cp'=MeCp, Ln=Yb)or Cp'LnCl₂(Cp'=Bu^tCp, Ln=Yb, Nd;Cp'=MeCp, Ln=Yb) together with BuLi were first found to catalyze the selective dimerization of butanal to butyl butyrate in moderate yields under mild conditions.The yields were found to be influenced by the structure of lanthanocene complexes.
