  (t(1/2) ca. 12 h) but accelerates the Si-H bond activation and Si-Si bond formation reactions. The catalysis promoted by 2a/3 proceeds even faster in the presence of NEt3 or THF (TOF > 1600 h(-1)), because these Lewis bases favor the monomeric form of 3, which in turn favors the formation of 4. On the other hand, the much more nucleophilic base quinuclidine suppresses the catalysis (TOF < 300 h(-1)) by hindering

  已经研究了甲基铝氧烷 (MAO) 在 Ni 催化的 PhSiH3 脱氢同系化中的作用，以设计具有明确定义的化学成分和结构的新型助催化剂。这些研究表明，双功能试剂 (Me2PCH2AlMe2)2, 3 等物质应作为 Si-Si 键形成反应的助催化剂。因此，发现 (1-Me-茚基)Ni(PPh3)Me、2a 和 3（Ni/Al 比率为 1:1）的组合将 PhSiH3 转化为具有转换频率的环状低聚物 (PhSiH)n（ TOF) > 500 h(-1)，比单独使用 2a 快 50 倍。详细的 NMR 研究表明，这种加速是由于中间体 (1-Me-茚基)Ni(Me)(Me2PCH2AlMe2), 4 的形成。该复合物中的 PMe2 部分与 Ni 中心的协调允许系留的 AlMe2 部分与 Ni-Me 部分相互作用，从而促进相当缓慢的 Al-Me/Ni-CD3 交换 (t(1/2) ca。 12 h) 但加速了

  5×104 Da. NMR studies have revealed that MAO methylates these complexes without ionizing the Nithienyl bond; this implies that the polymerization reactions likely follow a non-cationic mechanism similar to that catalyzed by the corresponding NiCCPh complexes studied previously. Complexes 1–5 reacted with CF3SO3H to produce the corresponding NiOSO2CF3 compounds by protonation at the α-C of the thienyl

  phthalimidato ligand is η1(N)-coordinated to Ni; the Ni−N bond is relatively short (1.895(4) Å), and the orientation of the imidato ligand is such that the planes bearing the atoms P, Ni, N and C9, N, C16 are rotated by ca. 76° with respect to each other. The hapticity of the indenyl ligand is characterized by an allyl-ene distortion (η5↔η3) and a partial localization of bonding inside the indenyl ring (η3↔η1

  The complexes (1-Me-Ind)(PR3)Ni-Cl (Ind = indenyl; R = Me (2), Cy (3), Bu (4), and (CH2)(2)(CF2)(5)CF3 (5)) have been prepared by the direct reaction of the corresponding (PR3)(2)NiCl2 with Li(1-Me-Ind) or via phosphine exchange reactions with (1-Me-Ind)(PR ' (3))Ni-CI (R ' = Ph (1) and Me). Solution NMR and single-crystal X-ray diffraction studies of the structures of 2 and 3 have allowed an analysis of the mode of coordination of the 1-Me-Ind ligand both in the solid state and in solution. Kinetic studies have shown that the substitution of PPh3 in (1-Me-Ind)(PPh3)Ni-Cl by PCy3 follows a second-order rate (associative mechanism) with the following kinetic parameters. K-2 (x 10(-2) M-1 s(-1)) = 1.1 +/- 0.1 at 233 K, 1.9 +/- 0.4 at 245 K, 15 +/- 2 at 284 EC, 21 +/- 2 at 293 K, and 34 +/- 7 at 303 K, DeltaH double dagger = 6.40 +/- 0.07 kcal/mol; DeltaS double dagger = -40 +/- 4 eu. The implications of these results for the mechanisms of the polymerization reactions catalyzed by these complexes have been discussed.
• Preparation and Characterization of (1-Me-indenyl)Ni(PR₃)(CC−Ph) (R = Cy, Ph) and Alkyne Polymerization Catalysis

  The complexes (1-Me-Ind)(PR3)Ni-CC-Ph (R = Ph and Cy) have been prepared and characterized spectroscopically and by means of single-crystal structural analyses. These compounds are inert toward the insertion of alkynes, but when combined with methylaluminoxane (MAO), they form active catalysts for the homogeneous polymerization of phenylacetylene. cis-Poly(Ph-CC-H) is thus obtained with M-w values in the range of 10(4) and relatively narrow polydispersities. The combination of the corresponding Ni-Cl complexes with MAO gives similar results with Ph-CC-H and also polymerizes 1-hexyne and 3-hexyne, but the degree of polymerization is much lower. Optimization studies have shown that the polymerization reactions give the best results with THF as solvent and a 1:10 ratio of Ni to MAO. Evidence is presented for the involvement in the catalytic cycle of bimetallic species with a Ni(mu-X)(mu-Me)Al core.
