  Tetra-, Penta-, and Hexanuclear Yttrium Hydride Clusters from Half-Sandwich Bis(aminobenzyl) Complexes Containing Various Cyclopentadienyl Ligands

  摘要：

  The novel series of half-sandwich tetrahydrofuran (THF)-free yttrium bis(arninobenzyl) complexes [(C(5)Me(4)R)-Y(CH(2)C(6)H(4)NMe(2-o))(2)] (R = SiMe(3) (1a), Me (1b), Et (1c), H (1d)) was prepared by treatment of [Y(CH(2)C(6)H(4)NMe(2-o))(3)] with C(5)Me(4)RH, and their reactions with H(2) and with PhSiH(3) in aromatic solvents or in THF were examined. The reaction of la with H(2) in benzene gave the pentanudear yttrium decahydride complex [{Cp'Y(mu-H)(2)}(5)] (Cp' = eta(5)-C(5)Me(4)SiMe(3)) (3), which could not be obtained by the reaction of the corresponding THF-coordinated dialkyl complex [Cp'Y(CH(2)SiMe(3))(2)(THF)] with H(2). The reaction of 1b with H(2) in toluene gave the partially hydrogenated tetranudear mixed aminobenzyl/hydride complex [(Cp*Y)(2)(CH(2)C(6)H(4)NMe(2-o))(mu-H)(3)](2) (4; Cp* = eta(5)-C(5)Me(5)), and no further hydrogenation reaction occurred, whereas the corresponding reaction of 1b with H(2) in THF gave the pentanuclear yttrium polyhydride complex [{Cp*Y(mu-H)(2)}(5) (THF)(2)] (5). Hydrogenolysis of the sterically less demanding C(5)Me(4)H-ligated complex 1d with H(2) in THF gave the tetranuclear octahydride complex [{Cp(H)Y(mu-H)(2)}(4)(THF)(4)] (6; Cp(H) = eta(5)-C(5)Me(4)H), which has one coordinating THF ligand on each metal atom. The hexanuclear yttrium dodecahydride complex {[Cp*Y(mu-H)(2)](6)} (7) was obtained by treatment of 1b with PhSiH(3) in benzene. The structures of 1a,b,d, 3, 4, {{(C(5)Me(4)Et)Y(mu-H)(2)}(5)(THF)(2)] (5'), 6, and 7 were determined by X-ray single-crystal diffraction studies.

  Hydrogenolysis of the dialkyl complexes [Y(η⁵‐C₅Me₄SiMe₂R)(CH₂SiMe₃)₂(THF)] (1a, R = Me; 1b, R = Ph) results in the formation of the tetranuclear dihydrido complexes [(η⁵‐C₅Me₄SiMe₂R)Y}₄(μ‐H)₄(μ₃‐H)₄(THF)₂] (2a, R = Me; 2b, R = Ph), characterized by NMR spectroscopy. 2a was studied by single crystal X‐ray diffraction. In the solid state, an unsymmetrical tetrahedral configuration of four [Y(η⁵‐C₅Me₄SiMe₃)] units is observed, two of which contain each one molecule of THF. Each yttrium atom is bonded to two μ₂‐ as well as three μ₃‐bridging hydrido ligands.

  摘要氢解二烷基络合物 [Y(η5-C5Me4SiMe2R)(CH2SiMe3)2(THF)]（1a，R = Me；1b，R = Ph），从而形成四核二氢配合物[(η5-C5Me4SiMe2R)Y}4(μ-H)4(μ3-H)4(THF)2]（2a，R = Me；2b，R = Ph），并通过核磁共振光谱进行表征。对 2a 进行了单晶 X 射线衍射研究。在固态下，观察到由四个[Y(η5-C5Me4SiMe3)]单元组成的非对称四面体构型，其中两个单元各含有一分子 THF。每个钇原子都与两个 μ2- 和三个 μ3 桥接的氢化物配位体结合。
