    Pyridine, isocyanide, carbodiimide and allene adducts of hexakis (trifluoromethyl t-botoxy) ditungsten. A comparison of ligand binding to W2(OtBu)6 and W2(OCMe2CF3)6
    摘要:
    W-2(OR)(6) compounds, where R = 'Bu and CMe2CF3, both reversibly bind pyridine in hydrocarbon solvents to form adducts W-2(OR)(6)L-2. Pyridine binds more strongly to the fluoroalkoxide but the structural parameters of the compounds W-2(OCMe2CF3)(6)(C6H5N)(2) and W-2(O'Bu)(6)(4-CH3C6H4N)(2) reveal an essentially identical W2O6N2 core with W-W = 2.39(1) Angstrom, W-O = 1.92-1.95 Angstrom and W-N = 2.26(1) Angstrom. Both compounds were crystallographically characterized in the space group C2/c and each molecule has rigorous C-2 symmetry. Allene and 1,3-di-p-tolylcarbodiimide form 1 : 1 adducts with W-2(OCMe2CF3)(6) in which the substrate is bound parallel to the M-M axis, i.e. mu-eta(2), eta(2)-C3H4 and mu-eta(2), eta(2)-ArNCNAr-W-2(OCMe2CF3)(6). Also W-2 (OCMe2CF3)(6) and W-2(OSi'BuMe2)(6) bind two equivalents of xylylisocyanide to afford W-2(OR)(6)(eta(1)-CNAr)(2). For W-2(OCMe2CF3)(6)(eta(1)-CNAr)(2), the molecular structure has been determined by X-ray crystallography and shows a nearly eclipsed central W2O6C2 skeleton with W-W = 2.44(1) Angstrom, W-O = 1.94(1) Angstrom (av.) and W-C = 2.14(1) Angstrom, whereas the W-W-O angles span the range 105-114 degrees, the W-W-C angles are 83(1)degrees. Similarly, W-2(OChle(CF3)(2))(4)(NMe2)(2) forms a bis adduct upon reaction with the isocyanide. However, the molecular structure of W-2(OCMe(CF3)(2))(4)(NMe2)(2)(eta(1)-CNAr)(2), shows a staggered arrangement of the two ligands about the ditungsten center where W-W = 2.382(1) Angstrom, W-O = 2.00(1) Angstrom (av.), W-N = 1.93(1) Angstrom (av.) and W-C = 2.14(1) Angstrom (av.) with a C-W-W-C dihedral angle of 41.9 degrees. These reactions and their products are compared for W-2(OR)(6) compounds where R = 'Bu,'BuMe2Si and CMe2CF3. (C) 1998 Elsevier Science Ltd. All rights reserved.

  • Spectroscopic properties of conjugated metalcarbon multiple bonds: synthesis and absorption spectra of the “dialkylidynes” (RO)3WCCW(OR)3 (OR = OCMe3, OCMe2CF3, OCMe2Et)

    ''Dialkylidyne'' (mu-dicarbido) complexes (RO)3W = C-C = W(OR)3 (OR = OCMe3, 1; OCMe2CF3, 2; OCMe2Et, 3) have been synthesized. A single crystal X-ray diffraction study performed on the t-butoxy complex 1 demonstrates that the molecule exists in a staggered D3d form in the solid state at -50-degrees-C. Complex 1 crystallizes in the rhombohedral space group R3BAR, a = 11.301(4) angstrom, alpha = 52.93(3)-degrees, Z = 1. Data were collected in the omega-2-theta-mode and refined to R = 0.039 and R(w) = 0.055. Absorption spectra of 1-3 in 2-methylpentane show a surprisingly large number of transitions as compared to the alkylidyne Me3CC = W(OCMe3)3 and the triply bonded dimer W2(OCMe3)6; while assigning the bands is not currently feasible due to the three-fold symmetry of the molecules, these observations suggest that the pi-clouds in 1-3 are conjugated in the excited state rather than localized.
    合成了一种二烃基底(mu-二碳化)复合物(RO)₃W=C-C=W(OR)₃(OR=OCMe₃,1;OCMe₂CF₃,2;OCMe₂Et,3)。对t-丁氧基复合物1进行单晶X射线衍射研究,结果表明该分子在-50℃的固态下以D₃d形式存在,该结构具有季戊烷骨架的畸变性。复合物1在菱方晶系空间群R₃B ARP中 crystallizes,a=11.301(4)Å,α=52.93(3),Z=1。数据采用ω-2θ模式收集,并以R=0.039和R(w)=0.055进行了精修。在2-甲基戊烷中1-3的吸收光谱显示,与烷基基底Me₃CC=W(OCMe₃)₃和三键二聚体W₂(OCMe₃)₆相比,其电荷跃迁数目异常繁多;尽管由于分子的三重对称性,目前无法对这些谱带进行明确归属,但这一观察表明复合物1-3的π电子云在激发态呈现共轭性而不显局部化。
