Synthesis, Characterization Of Complexes Tetrahydrofurfurlfluorenyl And (Me₃Si)₂NSiMe₂ Functionized Cyclopentadienyl Lanthanide Chloride

All experiments were performed under an atmosphere of dry argon with the rigid exclusion of air and moisture using standard Schlenk techniques.The synthesis, characterization of complexes tetrahydrofurfurlfluorenyl and (Me₃Si)₂NSiMe₂ functionized Cyclopentadienyl lanthanide chloride are reported.There are nine compounds in the paper.Reaction of C₄H₇OCH₂Br with 1 equivalent of C₁3H₉Li yielded C₄H₇OCH₂C₁3H₉(1) in 40% at 0℃. At -78℃, lanthanocene chlorides [ η⁵ :η¹-(C₄H₇OCH₂C₁3H₈)]₂LnCl[Ln=Nd(2); Ln=Dy(3); Ln=Pr(4); Ln=Ho(5); Ln=Sm(6).] were synthesiszed by the reaction of 2 equiv of tetrahydrofurfurlfluorenyl lithium with corresponding anhydrous lanthanide chorides in THF respectively in 61%. 73% 62% 67% yield. They are sensitive to air and moisture.They can be dissolved in DME THF and toluene easily and can't be dissolved in hexane. The mentioned complexes were characterized by elementary analyses,IR.Reaction of (Me₃Si)₂NLi with 4 equivalent Me₂SiCl₂ at room...
