  Sidearm Effects. Synthesis, Structural Characterization, and Reactivity of Rare Earth Complexes Incorporating a Linked Carboranyl-Indenyl Ligand with a Tethered Oxygen Atom

  摘要：

  New ether-functionalized carboranyl-indenyl hybrid ligands were prepared. They can prevent lanthanocene chlorides from ligand redistribution reactions and offer samarium(II) complexes unusual reactivities. Treatment of Me2SiCl(C9H6CH2CH2OMe) with 1 equiv of Li2C2B10H10 in toluene/Et2O afforded the monolithium salt [Me2SK9H5CH2CH2OMe)-(C2B10H11)]Li(OEt2) (2). Interaction of 2 with 1 equiv of n-BuLi in Et2O produced the dilithium salt [Me2Si(C9H5CH2CH2OMe)(C2B10H10)]Li-2(OEt2)(2) (3). Reaction of 3 with 1 equiv of LnCl(3) at room temperature gave the complex salts of general formula [{[eta(5):sigma-Me2Si(C9H5CH2CH2OMe)(C2B10H10)]Ln(THF)(mu-Cl)(3)Ln[eta(5):eta(1):sigma-Me2Si(C9H5CH2CH2OMe)(C2B10H10)]}(2){Li(THF)}]- [Li(THF)(4)] (Ln = Y (4), Yb (5)). Upon heating, 5 was converted into [eta(5):eta(1):sigma-Me2Si(C9H5CH2CH2OMe)(C2B10H10)]Yb(THF)(mu-Cl)(2)Yb[eta(5):eta(1):sigma-Me2Si(C9H5CH2CH2OMe)(C2B10H10)] (6) by (6) by eliminating LiCl. Treatment of 4 or 5 with 2 equiv of group 1 metal amides gave organo-rare-earth amide complexes [eta(5):eta(1):sigma-Me2Si(C9H5CH2CH2OMe)(C2B10H10)]Y(NHC6H3-2,5-Bu-t(2))-(mu-Cl)Li(THF)(3) (8) or [eta(5):eta(1):sigma-Me2Si(C9H5CH2CH2OMe)(C2B10H10)]Yb(NHC6H3-2,6-Pr-i(2))(mu-Cl)Li(THF)(3) (9). An equimolar reaction of SmI2 with 3 in THF generated, after addition of LiCl, [{[eta(5):sigma-Me2Si(C9H5CH2CH2OMe)(C2B10H10)](2)Sm}{Li(THF)}](n) (10) and [{eta(5):eta(1):eta(6)-Me-2-Si(C9H5CH2CH2OMe)(C2B10H10)Sm}(2)(mu-Cl)] [Li(THF)(4)] (11). In sharp contrast, a less reactive YbI2 reacted with 3 in THF, producing only salt metathesis product [eta(5):eta(1):sigma-Me2Si(C9H5CH2CH2OMe)(C2B10H10)]Yb(DME)(THF) (12). 12 reacted with 1 equiv of 3 to give the ionic complex {[(mu-eta(5):eta(2)):eta(1):sigma-Me2Si(C9H5CH2CH2OMe)(C2B10H10)](2)Yb}{Li(THF)(2)}(2) (13). All complexes were characterized by various spectroscopic techniques and elemental analyses. The structures of 5, 6, and 8-13 were further confirmed by single-crystal X-ray analyses.
