  • Transition‐Metal‐Free Cross‐Coupling by Using Tertiary Benzylic Organoboronates
    作者:Mitsutaka Takeda、Kazunori Nagao、Hirohisa Ohmiya
    DOI:10.1002/anie.202010251
    日期:2020.12.7
    The transition‐metal‐free cross‐coupling of alkyl or aryl electrophiles by using tertiary benzylic organoboronates is reported. This reaction involves the generation of tertiary alkyl anions from organoboronates in the presence of an alkoxide base and then their substitution reactions. This protocol allows the simple and efficient construction of quaternary carbon centers.

    A process for producing benzyllithium, benzylsodium and polyphenylene paradimethylene and analogs comprising dissolving toluene in an aprotic polar solvent in which toluene is more acidic than water, such as DMSO, under an inert atmosphere, such as argon, adding an alkali metal hydroxide, such as lithium or sodium hydroxide, to form the alkali metal anion of the benzyl cation and water then removing the solvent and water to obtain the solid alkali metal alpha-carbon toluene compound, which is best stored under hexane. This process also relating to toluene analogs such as parachloro toluene which thereby yields parachloro alkali metal alpha-carbon toluene which is then polymerized by heating with a suitable high-boiling solvent, such as dibutyl ether or dimethoxy ethane in the presence of a copper catalyst, such as copper sulfate or finely divided copper metal at approximately 170C for 5 hours to form polyphenylene paradimethylene. This process having the advantage of using alkali metal hydroxides instead of elemental alkali metals, a reaction occurring at ordinary temperatures, and a lower cost of the product. This process also allowing the economical production of polyphenylene paradimethylene which is not currently being manufactured.
    一种生产苄基苄基钠和聚对苯二甲烯及类似物的方法,包括在无溶剂中溶解甲苯,其中甲苯更酸性,例如DMSO,在惰性气氛下,例如气,添加碱属氢氧化物,例如氢氧化物,以形成苄阳离子的碱属阴离子和,然后去除溶剂和,以获得固体碱属α-碳甲苯化合物,最好存放在己烷中。该过程还涉及甲苯类似物,如对氯甲苯,从而产生对属α-碳甲苯,然后通过加热与适当的高沸点溶剂,如二丁基醚二甲氧基乙烷,在催化剂的存在下,例如硫酸铜或细分的属,在大约170摄氏度下反应5小时,形成聚对苯二甲烯。该过程具有使用碱属氢氧化物而不是元素碱属、在普通温度下发生反应以及产品成本较低的优点。该过程还允许经济生产目前尚未生产的聚对苯二甲烯。

    作者:A. L. Shabanov、N. M. Seidov、U. A. Gasanova、Z. O. Kakhramanova、M. M. Gasanova
    DOI:10.1134/s1070428009010047
    日期:2009.1
    Metalation of toluene and isopropylbenzene with alkali metal-crown ether complexes led to the corresponding α-metalated alkylbenzenes. Treatment of the latter in succession with solid carbon dioxide, water, and hydrochloric acid gave carboxylic or dicarboxylic acids in 65–78% yield. Metalation of isopropylbenzene with sodium or potassium crown ether complexes above 90°C was accompanied by cleavage
    用碱属-冠醚配合物将甲苯和异丙基苯属化,生成相应的α-属化烷基苯。依次用固体二氧化碳盐酸处理后者,可得到65-78%的羧酸或二羧酸。在高于90°C的条件下,用冠醚络合物对异丙苯进行属化时,会裂解聚醚环并形成有机属化合物,然后这些有机属化合物会与异丙苯反应生成2-sodio(potassio)-2-phenylpropane和开链低聚醚。
  • Relation between conformational structure, vibrational spectra and intramolecular excimer formation in 2,4-dimethyl-2,4-diphenylpentane

    rotations. IR analysis and intramolecular excimer formation indicate that 2,4-dimethyl-2,4-diphenylpentane exists in one of the most stable conformations in the crystalline state. In the liquid state higher-energy conformers are present. Fluorescence emission studies show that 2,4-dimethyl-2,4-diphenylpentane exhibits a higher efficiency of excimer formation than 2,4-diphenylpentane, because of the rather
    摘要 2,4-二甲基-2,4-二苯基戊烷的构象能计算已在明确考虑亚甲基键角灵活性的情况下进行。无论构象如何,该角度使能量最小化的值接近 126°。能量等值线是相对于主链键旋转给出的。分子内迁移率研究表明,预计有两种运动:第一种运动包括低活化能的运动,而第二组运动需要更高的活化能,并涉及围绕 CC 骨架键的大旋转。在所有情况下,苯环旋转都与链旋转密切相关。IR 分析和分子内准分子形成表明 2,4-二甲基-2,4-二苯基戊烷以结晶状态中最稳定的构象之一存在。在液态中存在更高能的构象异构体。荧光发射研究表明,2,4-二甲基-2,4-二苯基戊烷比2,4-二苯基戊烷具有更高的准分子形成效率,因为准分子与基态构象之间的能垒相当小。
