  • Synthesis and Crystal Structures of Two Monomeric Methylene Bis(diaminoalanes)
    作者:Klaus Knabel、Heinrich Nöth、Thomas Seifert
    DOI:10.1515/znb-2002-0717
    日期:2002.7.1

    Substitution of the Cl atoms of CH2(AlCl2)2 by 2,2,6,6-tetramethylpiperidino or bis(trimethylsilyl)- amino groups leads to monomeric methylene bis(diaminoalanes). These show a wide Al-C-Al bond angle as determined by X-ray crystallography and asymmetrically bonded amino groups in the piperidino derivative.

    CH2(AlCl2)2中的原子被2,2,6,6-四甲基哌啶基或双(三甲基基)基团所取代,产生了单体亚甲基双(二)。通过X射线晶体学测定,这些化合物展示了一个宽的Al-C-Al键角,并且在哌啶生物中存在非对称键合的基团。
  • Organometallic reaction mechanisms

    compared to the reactions of triethylaluminium with the same ketone. The results support the importance of a bridging alkyl group described by the formation of a six-centered transition state when two equivalents of a trialkylaluminum compound are allowed to react with a ketone in hydrocarbon solvent. The results also argue against a transition state described by two moles of trialkylaluminum compound complexed
    等2 ALCH 2 ALET 2(1)已被用来作为一种机械探针,以确定在三烷基化合物的两个当量的在烃溶剂中的该反应的过渡态的性质。在中制备1,并确定溶液组成。低温1个的1 H NMR数据1作为单(乙醚化物)表明醚被同时配位到两个原子上。1的反应将4-叔丁基环己酮在烃类溶剂中的含量与三乙基铝与相同的反应进行了比较。当在烃类溶剂中使两当量的三烷基化合物与反应时,结果支持形成六中心过渡态所描述的桥接烷基的重要性。该结果还反对了由两摩尔与羰基原子络合的三烷基化合物描述的过渡态。
  • Design and synthesis of phosphonate inhibitors of glutamine synthetase
    作者:G. King Farrington、Alok Kumar、Frederick C. Wedler
    DOI:10.1021/jm00394a022
    日期:1987.11
    Inhibitors 1-4 have been shown previously to undergo enzymatic phosphorylation by glutamine synthetase (GS). Phosphonates 6-9 were designed as chemically stable analogues of these phosphorylated inhibitors, incorporating either a tetrahedral sulfur group (6-8) (-S-, -SO-, -SO2-) or phosphinate (9) adjacent to methylphosphonic acid. Phosphonates 6-8 resemble the transiently stable phosphorylated methionine
    先前已经显示抑制剂1-4通过谷酰胺合成酶(GS)进行酶促磷酸化。膦酸6-9被设计为这些磷酸抑制剂化学稳定类似物,并结合了四面体基(6-8)(-S-,-SO-,-SO2-)或与甲基膦酸相邻的次膦酸(9)。膦酸6-8类似于暂时稳定的磷酸化甲酸砜(2),而9类似于磷酸化的2-基-4-膦酰基丁酸(4)。当作为细菌,哺乳动物和植物中谷酰胺合成酶抑制剂进行测试时,类似物9被证明是最有效的,相对于大肠杆菌酶,其Ki值为7.5 X 10(-5)M。分析6-9的抑制数据表明,用疏甲基取代桥接四面体(6-8)或次膦酸(9)的和末端磷酸会大大降低酶对抑制剂的亲和力。次膦酸上的负电荷与活性位点上的Mn2 +相互作用可导致GS对膦酸9的亲和力增强。

    Abstract Complexes of the general formula MX2·nRA1X2 have been synthesized by reaction of alkali-earth metal halides with alkyl-aluminium dihalides. Their properties, in comparison with those of analogous complexes of alkali metal halides are reported.

  • The Methylene-bridged Dialuminium Compound R<sub>2</sub>Al-CH<sub>2</sub>-AlR<sub>2</sub> [R=CH(SiMe<sub>3</sub>)<sub>2</sub>] as an Effective Chelating Lewis Acid – Adducts with Halides, Perchlorate and Isopropylamide
    作者:Werner Uhl、Christian Rösener、Christina Stefaniak、Tim Choy、Beate Jasper-Peter、Jutta Kösters、Marcus Layh、Alexander Hepp

    The new methylene-bridged dialuminium compound Aryl2Al-CH2-AlAryl2 1b was synthesised from Cl2Al-CH2-AlCl2 and four equivalents of LiAryl [Aryl=C6H2(2,4,6-i-Pr)3]. A 1 : 2 stoichiometric ratio of the starting compounds afforded the dimeric aluminium halide (Aryl2AlCl)2 (2) by dismutation. The coordination behaviour of the related, but more easily available dialuminium compound R2Al-CH2-AlR2 [R=CH(SiMe3)2] 1a was explored. It yields the Lewis acid base adducts [M][R2Al-CH2-AlR2(μ-X)] [3a, M=Li(TMEN)2, X=Cl; 3b, M=Li(TMEN)2, X=Br; 3c, M=K(18-crown-6), X=ClO4; 3d, M=Li(TMEN)2, X=NH(i-Pr)] with X residing in a bridging position between the two Al atoms as evident from NMR spectroscopy and X-ray crystallography (3b, 3c, 3d). Compound 3c is a unique example of a stable, in organic solvents soluble adduct that features a ClO4 - anion coordinated by an alkylaluminium compound via two of its oxygen atoms.

    由 Cl2Al-CH2-AlCl2 和四当量的 LiAryl [Aryl=C6H2(2,4,6-i-Pr)3]合成了新的亚甲基桥联二铝化合物 Aryl2Al- -AlAryl2 1b。起始化合物的化学计量比为 1:2,通过歧化得到二聚卤化 (Aryl2AlCl)2 (2)。研究还探讨了与之相关但更容易获得的二价化合物 R2Al- -AlR2 [R=CH(SiMe3)2] 1a 的配位行为。它产生了路易斯酸碱加合物 [M][R2Al- -AlR2(μ-X)] [3a,M=Li(TMEN)2,X=Cl;3b,M=Li(TMEN)2,X=Br;3c,M=K(18-冠-6),X=ClO4;3d,M=Li(TMEN)2,X=NH(i-Pr)],从核磁共振光谱和 X 射线晶体学(3b、3c、3d)可以看出,X 位于两个原子之间的桥接位置。化合物 3c 是在有机溶剂中稳定可溶的加合物的一个独特例子,其特点是 - 阴离子通过其两个原子与烷基化合物配位。
