  • Solvolysis of (4-Nitrophenoxy)ethylene Oxides
    作者:David S. Shipley、Angela M. Ross、Ram S. Mohan、Dale L. Whalen、Jane M. Sayer、Paul M. Serve、Donald M. Jerina

    (4-Nitrophenoxy)ethylene oxide (1a) (2-chloro-4-nitrophenoxy)ethylene oxide (1b), and (4-phenylphenoxy) ethylene oxide (1c) were synthesized. Rates of acid-catalyzed, noncatalyzed, and hydroxide ion-catalyzed reactions for is and Ib and rates of acid-catalyzed and noncatalyzed hydrolysis of 1c were measured in 0.1 M NaClO4 solutions. Acid-catalyzed hydrolysis of 1a is ca. 6200 times faster than that of 4-nitrostyrene oxide, and that of 1c is 57 times faster than that of styrene oxide. These increased rates are attributed to stabilization of developing positive charge on the acetal carbon by the phenoxy oxygen that is present in the substituted phenoxyethylene oxides but not in the styrene oxides. The pH-rate profiles for reaction of 1a and 1b in 1.0 M KCl solutions over the pH range 2-14 were determined. At intermediate pH, the rates of reaction of 1a and 1b in 1.0 M KCl solutions are ca. 6-8 times faster than the corresponding rates in 0.1 M NaClO4 solutions. From rate and product studies, these increased reaction rates in KCl solutions were attributed to bimolecular attack of chloride ion at the methylene carbon of the epoxide moiety, The reactivity of 1a is greater than that of 1b toward acid-catalyzed hydrolysis but less than that of 1b in both noncatalyzed and hydroxide ion-catalyzed hydrolysis. Compound 1c reacts about 73-fold faster than 1a in acid and about 11-fold faster in the noncatalyzed reaction. From reactivity considerations, it is proposed that H2O and HO- also add as nucleophiles to the methylene carbon of the epoxide moieties of 1a and 1b, whereas H2O adds to the acetal carbon of 1c.
    (4-硝基苯氧基)环氧乙烷(1a)、(2--4-硝基苯氧基)环氧乙烷(1b)以及(4-苯基苯氧基)环氧乙烷(1c)被合成出来。在0.1 M NaClO4溶液中,测定了1a和1b在酸催化、无催化和氢氧化物离子催化条件下的反应速率,以及1c在酸催化和无催化条件下的解速率。酸催化下,1a的解速率比4-硝基邻苯二甲酰乙烷快约6200倍,1c的解速率比苯基乙基砜快57倍。这些增加的速率归因于在取代的苯氧基环氧乙烷中存在、但在苯基乙基砜中不存在的苯氧基氧对乙酰碳上正在形成的正电荷的稳定作用。 在pH范围为2-14的1.0 M KCl溶液中,测定了1a和1b的pH-速率曲线。在中等pH下,1a和1b在1.0 M KCl溶液中的反应速率约为在0.1 M NaClO4溶液中相应速率的6-8倍。根据速率和产物研究表明,在KCl溶液中反应速率的增加是由于氯离子环氧乙烷部分的甲基碳的双分子攻击所致。1a对酸催化解的反应性大于1b,但在无催化和氢氧化物离子催化解中,1a的反应性小于1b。化合物1c在酸中解反应中比1a快约73倍,在无催化反应中则快约11倍。根据反应活性考虑,提出H2O和HO-作为亲核剂添加到1a和1b的环氧部分的甲基碳上,而 添加到1c的乙酰碳上。

  • Pyrolysis of some 13C-labeled glucans: a mechanistic study
    作者:Glenn R. Ponder、Geoffrey N. Richards
    DOI:10.1016/0008-6215(93)80003-w
    日期:1993.5
    An isotopic labeling study has been conducted to investigate the chemical mechanisms involved in the formation of certain pyrolysis products of glucans, specifically glycolaldehyde (GA), acetol (hydroxypropanone), acetic acid, and formic acid, which are the major non-aqueous components of the distillate fraction (−60°C condensate) of the pyrolyzate. 13C labels at C-1, C-2, and C-6 of the glucose rings

  • Investigation of the mechanism of dissociation of glycolaldehyde dimer (2,5-dihydroxy-1,4-dioxane) by FTIR spectroscopy
    作者:Varoujan A. Yaylayan、Susan Harty-Majors、Ashraf A. Ismail

    sugars. It exists in solid state, only in crystalline dimeric form as 2,5-dihydroxy-1,4-dioxane. However, in solution phase or during heating, it dissociates into different dimeric and monomeric forms. FTIR spectroscopy was used to study the effect of temperature, pH and solvent on the dissociation and chemical transformations of glycolaldehyde. The infrared spectra were recorded in different solvents as
    摘要乙二醇醛代表最简单的α-羟羰基部分-还原糖的常见结构特征。它以固态存在,仅以2,5-二羟基-1,4-二恶烷的结晶二聚体形式存在。但是,在溶液相或加热过程中,它会分解成不同的二聚体和单体形式。FTIR光谱用于研究温度,pH和溶剂对乙醇醛的离解和化学转化的影响。红外光谱是在30至85°C的时间和温度(加热和冷却循环期间)的函数下记录在不同溶剂中的。在加热期间,乙醇醛环状二聚体在羰基区域产生两个带,一个在1744cm -1,另一个在1728cm -1。这些带在加热周期中增加而在冷却周期中减小。数据表明,乙醇醛环状二聚体(2,5-二羟基-1,4-二恶烷)经历开环形成无环二聚体(1728 cm -1),该无环二聚体可再循环为2-羟基甲基-4-羟基-1 ,3-二氧戊环结构。无环二聚体还可以与烯二醇形式(1703cm -1)平衡解离成单体乙二醛(1744cm -1)。有证据表明,在中性或碱性溶液中,加热期间乙醇醛会氧化成乙醇酸。
