  Oxygenation of Simple Zinc Alkyls:  Surprising Dependence of Product Distributions on the Alkyl Substituents and the Presence of Water

  摘要：

  Oxygenation reactions of dialkylzinc solutions have been investigated. Me2Zn reacts with oxygen in the absence of water to give the bis(heterocubane) [(MeZn)(6)Zn(OMe)(8)], whereas Et2Zn and (Pr2Zn)-Pr-i afford the mono(heterocubanes) [(RZn)(4)(OR)(4)]. In the presence of small amounts of water (added during or after the oxygenation) the product types are reversed for Me2Zn and Et2Zn giving [(MeZn)(4)(OMe)(4)] and [(EtZn)(6)Zn(OEt)(8)], while being retained for (Pr2Zn)-Pr-i (giving [((PrZn)-Pr-i)(4)((OPr)-Pr-i)(4)]). Full characterization of all products by NMR spectroscopy, mass spectrometry, and elemental analyses is provided, and crystal structures of [(EtZn)(6)Zn(OEt)(8)] and [((PrZn)-Pr-i)(4)((OPr)-Pr-i)(4)] are reported. A rationalization of the different reactivities is attempted on the basis of DFT-calculated energies of some key reactants.

  对烷基锌与双氧反应的新见解

  摘要：

  报道了烷基锌与 O2 反应的研究，表明有机锌化合物的选择性氧化是可行的。[EtZn(azol)]n（唑 = 去质子化的 1-氮丙啶乙醇）与甲苯中过量的无水 O2 反应得到乙基过氧化锌 [EtOOZn(azol)]2[EtZn(azol)]2，而Me2Zn 和 O2 导致 Me6Zn7(OMe)8 簇以高产率分离。
