  • Effect of ion-pair formation between 1,4-benzosemiquinone and alkaline-earth metal cations on the semiquinone disproportionation equilibrium at physiological pH
    作者:Antonio E. Alegría、Betty Velázquez
    DOI:10.1007/bf00667220
    日期:1992.12
    The decrease in the 1,4-benzosemiquinone (BQ−.) disproportionation constant upon addition of either MgCl2 or BaCl2 was used to determine the corresponding semiquinone-M+2 ion pair formation constant in 10 mM cacodylic-cacodylate buffer, at pH 7.4, utilizing electron paramagnetic resonance (EPR) spectroscopy. These constants are 5.6±2.8 and 2.5±1.3 for magnesium and barium, respectively, at an ionic
    添加 MgCl2 或 BaCl2 后 1,4-苯并半醌 (BQ-.) 歧化常数的降低用于确定相应的半醌-M+2 离子对形成常数在 10 mM cacodylic-cacodylate 缓冲液中,pH 7.4,利用电子顺磁共振 (EPR) 光谱。在离子强度为 1.0 时,的这些常数分别为 5.6±2.8 和 2.5±1.3。BQ- 的减少。由于离子对的形成,在添加 MgCl2 或 时也检测到 g 值,MgCl2 比 更明显。通过将这些盐添加到 BQ- 中,质子耦合常数没有变化。包含解决方案。如果加入浓度高达 3.0M 的 KCl 或 Nacl,则未检测到离子对形成。

  • Thermodynamics of semiquinone disproportionation in aqueous buffer
    作者:Antonio E. Alegría、Marcos López、Norberto Guevara
    DOI:10.1039/ft9969204965
    日期:——
    The thermodynamic parameters, K-disp, Delta H degrees and Delta S degrees, controlling the disproportionation of semiquinones derived from 1,4-benzoquinone (BQ), 1,4-naphthoquinone (NQ), 2-methylbenzoquinone (MBQ), menadione (MNQ), naphthazarin (NZQ) and quinizarin (QNZ), have been determined. Smaller disproportionation constants, K-disp, are observed upon addition of a fused benzene ring to the semiquinone structure. Negative enthalpies and positive entropies of disproportionation govern the disproportionation equilibria. Addition of OH groups to the 5 and 8 positions in NQ(.-) displaces the disproportionation equilibrium to the semiquinone probably due to intramolecular hydrogen bonding.
  • Synthesis and electrochemical properties of benzo[b]naphtho[2,3-e][1,4]-dioxin-6,11-quinones and their N,N'-dicyano quinone diimine derivatives
    作者:Tomasz Czekanski、Michael Hanack、James Y. Becker、Joel Bernstein、Shmuel Bittner、Leah Kaufman-Orenstein、Dina Peleg
    DOI:10.1021/jo00004a042
    日期:1991.2
    The reaction of 2,3-dichloro-1,4-naphthoquinone (1) and catechols 2 in pyridine affords a series of substituted benzo[b]naphtho[2,3-e][1,4]dioxin-6,11-quinones 3. The latter compounds are transformed to the corresponding N,N'-dicyano quinone diimines 4, by treating them with N,N'-bis(trimethylsilyl)carbodiimide. The electrochemical studies of compounds of the type 3 and 4 in DMF and CH2Cl2, respectively, by means of cyclic voltammetry are reported. The experimental reduction potentials provide information on electron-electron repulsion in the dianionic states of 3 and 4, and hence on their potential use as acceptor components in charge-transfer complexes and organic conductors.
