  • Preformed π-Allyl Iron Complexes as Potent, Well-Defined Catalysts for the Allylic Substitution
    作者:Michael Holzwarth、André Dieskau、Misbah Tabassam、Bernd Plietker
    DOI:10.1002/anie.200901930
    日期:2009.9.14
    Reanimation: Catalytically inactive π‐allyl iron complexes are “reanimated” upon addition of N‐heterocyclic carbene ligands such as 1,3‐dimesitylimidazolin‐2‐ylidene (SIMES). A comparison of stoichiometric and catalytic allylic alkylation reactions shows the π‐allyl mechanism to be active in this catalytic system.
    复活:添加N-杂环卡宾配体(例如1,3-二苯甲酰咪唑啉-2-亚基(SIMES))后,具有催化活性的π-烯丙基络合物将“复活”。化学计量和催化烯丙基烷基化反应的比较表明,π-烯丙基机理在该催化体系中具有活性。
  • Reactivity of (η3-allyl)dicarbonylnitrosyl iron complexes with dimethyl malonate and diisobutyl malonate

    In this paper, we describe the reactivity of our previously reported (η3-allyl)dicarbonylnitrosyl iron complexes (1–9). In this context, stoichiometric reactions of 1–9 with dimethyl malonate and di-iso-butyl malonate were carried out. The regioselectivity of the resulting products (10–25) was determined by gas chromatoraphic analysis of reaction mixtures. These products were purified by column chromatography and then structurally characterized by IR, 1H NMR, 13C NMR spectroscopies and mass spectrometry. Effect of different ligands L (L = CO, PPh3, SIMES (1,3-di-tert-butylimidazolium hexafluoro phosphate), BUSI(1,3-bis(2,4,6-trimethyl-phenyl)-4,5-dihydro-3H-imidazol-1-ium hexafluorophosphate)) and their influence on the substitution pattern has also been studied. The introduction of variable substituents exhibited diverse reactivities. Generally, it was observed that the reactivity decreased by increasing the size of substituentin (η3-allyl)dicarbonylnitrosyl iron complexes (1–9). Strong impact on the reactivity was observed due to substitution pattern of the allyl moiety. A considerable reduction in the conversion ratio from 81% to 68% was observed in repositioning the substituent from C-3 to C-2 position.
    在本文中,我们描述了我们之前报道的(η3-烯丙基)二羰基亚硝基配合物(1–9)的反应性。在此背景下,进行了1–9与二甲基马来酸酯和二异丁基马来酸酯的化学计量反应。通过气相色谱分析反应混合物,确定了所得到的产物(10–25)的区域选择性。这些产物通过柱色谱纯化,然后通过红外光谱、1H NMR、13C NMR光谱和质谱进行结构表征。也研究了不同配体L(L = CO, PPh3, SIMES (1,3-二-tert-丁基咪唑磷酸盐), BUSI(1,3-双(2,4,6-三甲基苯)-4,5-二氢-3H-咪唑-1-磷酸盐))及其对取代模式的影响。引入可变取代基表现出多样的反应性。一般观察到,通过增大取代基的大小,(η3-烯丙基)二羰基亚硝基配合物(1–9)的反应性降低。由于烯丙基部分的取代模式,对反应性产生了明显的影响。从C-3位置移位到C-2位置时,转化率从81%显著降低至68%。
