  A Convenient Method for Production of Thionitrites and Disulfides Under Mild and Heterogeneous Condition

  摘要：

  Thiols can be readily converted to their corresponding thionitrite with a combination of inorganic acidic salts and sodium nitrite in dichloromethane at room temperature. Disulfides result from the homolytic cleavage of the sulfur-nitrogen bond of the unstable thionitrite and subsequent coupling of the resultant thiyl radicals.

  Nitroso group transfer from N-nitrososulfonamides to thiolate ions. Intrinsic reactivity

  摘要：

  The nitroso group transfer from N-nitrososulfonamides to thiolate ions was studied. Based on the results, the reaction rate is strongly dependent on the nature of the leaving group (alpha(1g) approximate to -1.30), but virtually independent of the basicity of the thiol (beta(nuc) approximate to 0-10)This dependence is ascribed to the presence of a nucleophile desolvation equilibrium (beta(d)) that is followed by the attack of the thiolate ion on the nitroso group (beta'(nuc)) via a concerted mechanism. The equilibrium constants for the loss of a nitroso group from a nitrosothiol and an N-nitrososulfonarni de were used to obtain the equilibrium constants for the different reactions involved. By using rate-equilibrium correlations, the parameters alpha(norm)(1g) ,beta(d), and beta('norm)(nuc) were obtained. (c) 2006 Elsevier Ltd. All rights reserved.

  nitrosoguanidines react through the corresponding neutral form, and the nucleophiles in the thiolate anion form to give the corresponding S-nitrosothiol. Regarding cysteine, the existence of three macroscopic acidity constants influenced the kinetic behavior of the transnitrosation reaction. Transnitrosation rates (ktr) of the two possible nucleophilic species were obtained and it was found that NOBMG has lower

  在1中研究了亚硝基从1-亚硝基1-甲基3-甲苯磺酰胍（NOTSG）和1-亚硝基1-甲基3-苯甲酰胍（NOBMG）转移到某些硫醇（包括氨基酸半胱氨酸）。 pH范围在7到12之间。 测得的反硝化的表观双分子速率常数（k tr app）显示出钟形的pH依赖性，清楚地表明两个亚硝基胍都通过相应的中性形式反应，并且以硫醇盐阴离子形式的亲核试剂产生相应的S-亚硝基硫醇。关于半胱氨酸，三个宏观酸度常数的存在影响了反硝化反应的动力学行为。亚硝化率（k tr）获得了两种可能的亲核物质，发现由于苯甲酰基的吸电子效应较低以及由于分子内氢的建立可能使阴离子结构稳定，因此NOBMG具有较低的硫醇反硝化能力键。所述ķ TR，计算所研究的亲核试剂的值，并建立了一个布朗斯台德型积给出意想不到底片β NUC（β NUC（NOBMG）= - 0,17和β NUC（NOTSG）= - 0,11）。非典型β NUC值归因于需要对亲核试剂的前面去溶剂。

  Using UV-vis spectrometrical measurements, equilibrium constants for NO transfer between S-nitroso-N-acetyl-penicillamine (SNAP) and different thiols as well as kinetic data for NO transfer from S-nitroso bovine serum albumin (BSANO) to thiols have been obtained, NO transfer from SNAP to other primary/secondary thiols are thermodynamically favorable, whereas other S-nitrosothiols exhibit similar NO transfer potential. The obtained Gibbs free energy, enthalpy and entropy data indicated that NO transfer reactions from SNAP to four thiols are exothermic with entropy loss. The kinetic behavior of BSANO/RSH transfer can be related to both the acidity of sulfhydryl group and the electronic structure in thiol. (C) 2001 Elsevier Science Ltd. All rights reserved.
