Synthesis of Rare earth catalyst LLaN(TMS)2·DME(L=3,5-But2-2-HO-C6H2CH-NH-C5H4N) and catalytic behavior for polymerization of rac-lactide

摘要：

　　A dianionic phenoxyamido ligand was the first to be used to stabilize organo-rare-earth mental amido complex.Amine elimination reaction of LaN(SiMe3)23(THF)2 with 3,5-Bute-2-HO-C6H2CH-NH-C5H4N in a 1∶1 molar-ratio gave the anionic phenoxyamido neodymium amide LLaN(TMS)2.DME (1) in a high isolated yield.Furthemore,the catalytic behavior of complex 1 for the ring-opening polymerization of rac-lactide was explored.
