• A convenient route to distannanes, oligostannanes, and polystannanes
  作者：Aman Khan、Robert A. Gossage、Daniel A. Foucher

  The quantitative conversion of the tertiary stannane (n-Bu)₃SnH (2) into (n-Bu)₆Sn₂ (4) was achieved by heating the neat hydride material under low pressure or under closed inert atmosphere conditions. A 31% conversion of Ph₃SnH (3) to Ph₆Sn₂ (5) was also observed under low pressure; however, under closed inert atmosphere conditions afforded Ph₄Sn (6) as the major product. A mixed distannane, (n-Bu)₃SnSnPh₃ (7), can also be prepared in good yield utilizing an equal molar ratio of 2 and 3 and the same reaction conditions used to prepare 4. This solvent-free, catalyst-free route to distannanes was extended to a secondary stannane, (n-Bu)₂SnH₂ (8), which yielded evidence (NMR) for hydride terminated distannane H(n-Bu)₂SnSn(n-Bu)₂H (9), the polystannane [(n-Bu)₂Sn]_n (10), and various cyclic stannanes [(n-Bu)₂Sn]_n=5,6 (11, 12). Further evidence for 10 was afforded by gel permeation chromatography (GPC) where a broad, moderate molecular weight, but highly dispersed polymer, was obtained (M_w = 1.8 × 10⁴ Da, polydispersity index (PDI) = 6.9) and a characteristic UV–vis absorbance (λ_max) of ≈370 nm observed.

  在低压或封闭的惰性气氛条件下加热整齐的氢化物材料，可实现叔锡烷 (n-Bu)3SnH (2) 向 (n-Bu)6Sn2 (4) 的定量转化。在低压条件下，Ph3SnH (3) 转化为 Ph6Sn2 (5) 的转化率为 31%；但在封闭的惰性气氛条件下，主要产物为 Ph4Sn (6)。利用等摩尔比的 2 和 3 以及用于制备 4 的相同反应条件，还可以制备出混合二烷烃 (n-Bu)3SnSnPh3 (7)，收率很高。这种无溶剂、无催化剂的二烷烃路线扩展到了仲烷--(n-Bu)2SnH2 (8)，得到了氢化物末端二烷烃 H(n-Bu)2SnSn(n-Bu)2H (9)、聚烷烃 [(n-Bu)2Sn]n (10) 和各种环状烷烃 [(n-Bu)2Sn]n=5,6 (11, 12)的证据（核磁共振）。凝胶渗透色谱法（GPC）进一步证明了 10 的存在，在该色谱法中，得到了一种宽泛、分子量适中但高度分散的聚合物（Mw = 1.8 × 104 Da，多分散指数（PDI）= 6.9），并观察到其特征紫外可见吸光度（λmax）≈370 nm。

  The use of metal hydrides such as NaBH4 as hydrogen-storage materials has recently received substantial research attention on account of the worldwide demand for the development of efficient hydrogen-production, -storage, and -transportation systems. Here, we report the quantitative production of H2 gas from a germanium hydride, Ph2GeH2, mediated by an iron catalyst at room temperature via dehydrogenative

  考虑到全世界对开发有效的氢气生产、储存和运输系统的需求，使用金属氢化物如 NaBH 4作为储氢材料最近受到大量研究关注。在这里，我们报告了由氢化锗 Ph 2 GeH 2定量生产 H 2气体，在室温下由铁催化剂介导，通过脱氢偶联，伴随着 (GePh 2 ) 5的形成。特别重要的是，Ph 2 GeH 2可以很容易地从 (GePh 2 ) 5中回收通过分别在 0 °C 或 40 °C下与 1 个大气压的 H 2或 PhICl 2 / LiAlH 4接触。基于四种中间体铁物种的分离，提出了 Ph 2 GeH 2铁催化脱氢偶联的详细反应机理。

• Air activated organotin catalysts for silicone curing and polyurethane preparation
  作者：Bernard Jousseaume、Nicolas Noiret、Michel Pereyre、Annie Saux、Jean Marc Frances

  DOI：10.1021/om00015a042

  日期：1994.3

  Upon exposure to air, 1,2-bis(acyloxy)tetraalkyldistannanes incorporated in mixtures of either silicone oils and curing agent, or of isocyanates and alcohols, are oxidized to 1,3-bis(acyloxy)tetraalkyldistannoxanes which show excellent catalytic properties for curing silicones or for preparing polyurethanes. Under nitrogen, they induce longer pot-lives than the usual bis(acyloxy)dialkylstannane catalysts. Peralkyl-polycyclostannanes, obtained either by the palladium-catalyzed decomposition of dialkylstannanes or by reduction of dichlorodialkylstannanes with metals, are also very good latent catalysts for silicone curing. When incorporated into reactive mixtures under nitrogen, they do not catalyze the condensation. Upon exposure to air, they are oxidized to active catalysts which cure silicones. These di- or polystannanes can be considered air-activated latent organotin catalysts.
