  • Copper-Catalyzed Regioselective and Stereoselective Coupling of Grignard Reagents with Pent-1-en-4-yn-3-yl Benzoates: A Shortcut to (<i>Z</i>)<i>-</i>1,5-Disubstituted Pent-3-en-1-ynes from Accessible Starting Materials

    Copper-catalyzed coupling of Grignard reagents with pent-1-en-4-yn-3-yl benzoates occurs regioselectively at the terminal alkenyl carbon rather than the alkynyl site, leading to the stereoselective formation of unexpected (Z)-1,5-disubstituted pent-3-en-1-ynes without generation of the initially expected alkenyl allene products. By using easily accessible starting materials, this reaction can provide

  • Synthesis and characterization of some octaalkyl substituted lead phthalocyanines and unexpected variations in lead lability arising from the position of substituents and their chain length

    The preparation of some peripherally substituted (2,3,9,10,16,17,23,24) and non-peripherally substituted (1,4,8,11,15,18,22,25) octaalkyl lead(II) phthalocyanines with different alkyl chain lengths (6, 7, 8 or 9 carbons) is described and a comparison of some of their properties reported. X-ray structure analyses of the isomeric peripheral and non-peripheral octakis(octyl)phthalocyaninato lead(II) compounds reveal a greater degree of distortion of the ligand ring system from planarity in the former derivative. The series of peripherally substituted octaalkyl lead(II) phthalocyanines exhibit columnar liquid crystal behavior whereas the non-peripherally substituted isomers do not. The lability of the lead ion was investigated using 1 H NMR spectrometry under a specific set of conditions (8.8 × 10-4 M solutions of the phthalocyanine in d8-toluene containing d4-acetic acid 2.06 × 10-5 M). All the compounds underwent acid catalyzed demetalation at rates dependent upon the location of the substituents and, more surprisingly, the chain length of the alkyl groups. Under these conditions the lead ion within each of the peripherally substituted octaalkyl lead phthalocyanines was more labile than that in the non-peripherally substituted isomer.

    本文介绍了一些外周取代(2,3,9,10,16,17,23,24)和非外周取代(1,4,8,11,15,18,22,25)、具有不同烷基链长度(6、7、8 或 9 个碳原子)的八烷基酞菁铅(II)的制备方法,并对它们的一些性质进行了比较。对同分异构的外周和非外周辛基酞菁(II)化合物的 X 射线结构分析表明,前者衍生物配体环系统的平面变形程度更大。外周取代的八烷基酞菁铅(II)系列表现出柱状液晶行为,而非外周取代的异构体则没有。在一组特定条件下(酞菁在含有 2.06 × 10-5 M d4-乙酸的 d8-甲苯中的 8.8 × 10-4 M 溶液),使用 1 H NMR 光谱法研究了离子的稳定性。所有化合物都在酸催化下发生了脱属反应,脱属的速度取决于取代基的位置,更令人惊讶的是取决于烷基的链长。在这些条件下,外周取代的八烷基酞菁铅中的离子比非外周取代的异构体中的离子更易变。
  • Nickel-Catalyzed Ring-Opening C–O Functionalization of <i>peri</i>-Xanthenoxanthenes for 8-Substituted Binaphthol Synthesis

    Herein, we disclose the Ni-catalyzed ring-opening C–O functionalization of peri-xanthenoxanthenes using Grignard reagents that forms 8-monofunctionalized binaphthols. 1,2-Bis(dicyclohexylphosphino)ethane was the best ligand for alkylations and ICy for arylation. After mechanistic investigations, we assumed that the reaction proceeds via C–O reduction and subsequent C–O functionalization. To verify
    在本文中,我们公开了使用格氏试剂形成8-单官能化联萘酚的Ni-催化的邻黄嘌呤氧杂蒽的开环C–O功能化。1,2-双(二环己基膦基)乙烷是烷基化和ICy芳基化的最佳配体。经过机理研究,我们假设反应是通过C–O还原和随后的C–O官能化进行的。为了验证机理,分离了还原后的中间体。此外,研究了在光学拆分后使用8-辛基联萘酚的不对称加成反应。

  • Micellar extraction of the lanthanide ions from acidic media
    作者:Yu. G. Elistratova、A. R. Mustafina、D. A. Tatarinov、V. F. Mironov、A. I. Konovalov

    A procedure of micellar extraction of the lanthanide ions (La, Gd, and Lu) from nitric acid media based on the use of novel phosphine oxide derivatives is developed. In the micellar extraction, complexes of the lanthanide ions with the extractant in the ratio of 1 : 2 (metal : extractant) form. The dependence of the selectivity of extraction on the length of hydrophobic radicals attached to the P=O group was shown. The conditions of the selective micellar extraction in the series La > Gd > Lu with the use of an extractant containing octyl substituents at the P=O group were found.
    开发了一种基于使用新型氧化膦衍生物硝酸介质中胶束萃取系离子(La、Gd 和 Lu)的方法。在胶束萃取中,系元素离子与萃取剂以 1:2(属:萃取剂)的比例形成络合物。显示了萃取选择性对连接到 P=O 基团的疏基团长度的依赖性。找到了使用 P=O 基团上含有辛基取代基的萃取剂对 La > Gd > Lu 系列中的选择性胶束萃取的条件。
