  Carbon versus Silicon Bridges. Synthesis of a New Versatile Ligand and Its Applications in Organolanthanide Chemistry

  摘要：

  A new carbon-bridged versatile ligand Me2C(C9H7)(C2B10H11) (1) has been designed and successfully prepared by treatment of Li2C2B10H10 with 1 equiv of 6,6-dimethylbenzafulvene followed by hydrolysis with a saturated NH4Cl aqueous solution. I can be conveniently converted into the monoanion [Me2C(C9H6)(C2B10H11)]Li (2) and the dianion [Me2C(C9H6)(C2B10H10)]Li-2 (3) by treatment with 1 or 2 equiv of n-BuLi, respectively Both NaNH2 and Nail can only convert 1 into the monoanion, but cannot deprotonate the CH proton of the carborane cage in I. These results differ significantly from those of a closely related analogue, Me2Si(C9H7)(C2B10H11). Treatment of SmI2 with 1 equiv of 3, followed by reaction with 1 equiv of 2, gave the redox product rac-[Li(DME)(2)][{eta(5):sigma-Me2C(C9H6)(C2B10H10)}(2)Sm] (4) 4 can also be prepared by reaction of SmI2 with 1 equiv of 3 in a relatively lower yield. These two reactions may undergo different pathways, an intramolecular electron-transfer pathway for the former and an intermolecular electron-transfer pathway for the latter. The latter reaction can be accelerated by addition of CS2, or PhC=CPh, which led to the isolation of rac-[Li(THF)(4)][{eta(5):sigma-Me2C(C9H6)(C2B10H10)}(2)Sm](5). Unlike the SmI2 case, an equimolar reaction between 3 and YbI2 afforded the Yb(II) compound [eta(5):sigma-Me2C(C9H6)(C2B10H10)]Yb(DME)(2) (6). 6 can react with 1 equiv of 2 to generate a C-H bond reduction product, rac[Li(DME)(3)][(eta(5):sigma-M(e)2C(C9H6)(C2B10H10)}(2)Yb]. C6H5CH3 (7) Reaction of LnCl(3) with 1 or 2 equiv of 2 yielded organolanthanide dichloride and monochloride compounds, respectively, [eta(5)-Me2C(C9H6)(C2B10H11)]GdCl2(THF)(2) (15) and [eta(5)-Me2C(C9H6)(C2B10H11)](2)LnCl(THF)(OEt2) (Ln = Y (8), Yb (9)). Treatment of 9 with 1 or 2 equiv of MeLi gave deprotonation products rac- [(eta(5):sigma-Me2C(C9H6)(C2B10H10)}(eta(5)-Me2C(C9H6)(C2B10H11)}]Yb(mu-Cl)Li(DME)(2) (10) and rac-[Li(DME)(2)][{eta(5):sigma-Me2C(C9H6)(C2B10H10)}(2)Yb] (11), respectively.Reaction of LnCl(3) with 2 equiv of 3 also afforded ionic compounds rac-[Li(DME)(2)][(eta(5):sigma-Me2C(C9H6)(C2B10H10)}(2)Ln] (Ln = Yb (11), Nd (12), Er (13)). Recrystallization of 7 from a mixed solvent of toluene/DME (10:1) gave meso-[Li(DME)(3)][(eta(5):sigma-Me2C(C9H6)(C2B10H10)}(2)Yb]. 2C(6)H(5)CH(3) (14) All of these compounds were fully characterized by various spectroscopic and elemental analyses. The molecular structures of 4-7, 11, 12, and 14 have been confirmed by single-crystal X-ray analyses. The structural analyses reveal that the anions in 7 (or 11) and 14 are one pair of diastereomers.

  The new inorganic/organic hybrid ligand [NMe3H][Me2C(C9H7)(C2B9H11)] was prepared via a selective deboration of Me2C(C9H7)(C2B10H11) with piperidine in ethanol. Reaction of the ligand with Zr(NMe2)(4) provided the neutral group 4 metal amide complex trans-[eta(5):eta(5)-Me2C(C9H6)(C2B9H10)]Zr(NMe2)(NHMe2) (3) through an amine elimination reaction. Treatment of the trianionic salt of the ligand with MCl4(THF)(2) gave the mixed sandwich complexes trans-[eta(5):eta(5)-Me2C(C9H6)(C2B9H10)}MCl2][Na(DME)(3)] (M = Zr (4) Hf (5)). Complex 4 reacted with KCH2Ph, C5H5Na, or NaNH(C6H3-2,6-Me-2) to afford trans-[eta(5): eta(5)-Me2C(C9H6)(C2B9H10)}ZrCl(CH2C6H5)][Na(DME)(3)](6), trans-[eta(1):eta(5)-Me2C(C9H6)(C2B9H10)]ZrCl(eta(5)- C5H5)}Na(DME)(3)} (7), or trans- [eta(5):eta(5)-Me2C(C9H6)(C2B9H10)]Zr(NHC6H3Me2)(THF) (8), respectively. Both 6 and 7 were thermally stable, and no NaCl elimination was observed upon heating their DME solutions. Complex 4 also reacted with excess NaH in THF to generate the ring-opening product trans-[eta(5):eta(5)-Me2C(C9H6)(C2B9H10)]Zr(OCH2CH2CH2CH3)(THF) (9). In the presence of excess MAO (methylalumoxane), complexes 3, 4, and 6 were active catalysts for ethylene polymerization. All complexes were fully characterized by various spectroscopic techniques and elemental analyses. Some were further confirmed by single-crystal X-ray analyses.
