The synthesis, characterization and application of rare earth borohydride compounds are summarized. The rare earth borohydride compounds have structural diversity and high catalytic activity for organic synthesis. They are not only useful as catalysts for the polymerization of lactones, lactides and methyl methacrylate , But also can catalyze the polymerization of mono- and bi-component olefins, especially the rare earth borohydride compounds with large groups as the skeleton, as the organic polymerization catalyst. The ligand framework usually coordinates with the rare earth metal center in a multi-tooth mode, Of the three-dimensional structure of the rare earth borohydride compounds have a great impact on the performance of different monomer polymerization initiated with high catalytic activity is conducive to the polymer molecular weight and distribution control for the synthesis of highly stereoselective polymers and the function The modification of the material provides a very effective catalyst, expounds the catalytic performance of rare earth borohydride compounds for the polymerization reaction, and prospects for its application in organic synthesis are also forecasted.
