  Electrosyntheses from Aromatic Aldehydes in a Flow Cell. Part II. The Cross-Coupling of Benzaldehydes to Unsymmetrical Diols.

  摘要：

  It is demonstrated that the reduction of mixtures of two benzaldehydes in acidic water-methanol in a membrane flow cell with a lend cathode can lead to a mixture of diols including the unsymmetrical diol, e.g. 4-F-C6H4-CH(OH)-CH (OH)-C6H5. In the conditions employed, the ratio of the three diol products follows the statistical distribution expected for the coupling of two different radical intermediates produced in the same ratio as the concentrations of their precursors. The yield and current efficiency for the diols are excellent when the pH and potential are selected so that a 1e(-) reduction of both benzaldehydes occurs. The yield of unsymmetrical dimer based on one reactant can be increased substantially by using the other carbonyl compound as a sacrificial reagent.

  We demonstrate N-phosphorylation and N-thiophosphorylation of unprotected aminonucleosides in aqueous media. N-Phosphorylations using phosphoric chloride and N-thiophosphorylations using thiophosphoryl chloride were explored as functions of pH using 5′-amino-5′-deoxyguanosine as substrate. These reagents were compared to phosphodichloridate and thiophosphodichloridate ions, and the methodology was applied to other aminonucleosides. S-Alkylations of the nucleoside N-thiophosphoramidates were investigated as functions of pH and alkylating agent.

  我们在水介质中证明了无保护氨基核苷的N-磷酸化和N-硫磷酸化。以5'-氨基-5'-脱氧鸟苷为底物，探索了使用磷酰氯进行N-磷酸化和使用硫磷酰氯进行N-硫磷酸化作为pH值的函数。将这些试剂与磷二氯酸酯和硫磷二氯酸酯离子进行了比较，并将该方法应用于其他氨基核苷。以pH值和烷基化剂为函数，研究了核苷N-硫磷酰胺的S-烷基化。
• Reaction of Nitrates with Liquid Sulphur Dioxide

  catalyse the formation of polysulphones from liquid mixtures of olefines and sulphur dioxide1, but the mechanism of catalysis has never been clarified. It is now suggested that the effective catalyst is nitrogen dioxide and/or the sulphite radical ion formed as the primary products of the reaction between nitrates and sulphur dioxide. The following observations are consistent with this suggestion:

  一段时间以来，人们已经知道无机硝酸盐可催化由烯烃和二氧化硫的液体混合物形成聚砜1，但催化机理从未阐明。现在建议有效的催化剂是二氧化氮和/或作为硝酸盐和二氧化硫之间反应的主要产物形成的亚硫酸根离子。以下观察结果与该建议一致：

  In the pulse radiolysis of concentrated sulfuric acid solutions, the absorption spectrum and the molar absorption coefficient (1600 dm3 mol–1 cm–1) of the sulfate radical are unchanged up to 10 mol dm–3 H2SO4, suggesting that the sulfate radical exists in the dissociated form (SO–4). Two formation processes for the sulfate radical have been directly demonstrated in sulfuric acid and hydrogensulfate

  在浓硫酸溶液的脉冲辐，所述吸收光谱和摩尔吸光系数（1600分米3摩尔-1厘米-1的硫酸根的）保持不变，至多10mol分米-3 ħ 2 SO 4，这表明硫酸根以离解形式存在（SO – 4）。在硫酸和硫酸氢盐溶液中已直接证明了硫酸根的两种形成过程：一种在电子脉冲持续时间内完成的快速过程，另一种在微秒时间内发生的缓慢过程。对于硫酸盐溶液，仅观察到快速形成过程。在硫酸溶液中，缓慢形成的过程是OH + HSO – 4 →H 2 O + SO – 4（4.7×10 5 dm 3 mol –1 s –1）和OH + H 2 SO 4 →HSO 4 + H 2 O →SO – 4 + H 3 O +（1.4×10 7 dm 3 mol –1 s –1），快速形成过程是辐射对硫酸的直接作用，其G值为（2.7±0.4）×10 –2分子eV –1。（OH + SO – 4）和H的产率可量化为：G（OH + SO

  Reaction of 4,4′,4″-tri(tert-butyl)-2,2′:6′,2″-terpyridine (terpy*) with gaseous SO2–O2 mixtures and [PdCl2(MeCN)2] followed by aqueous workup affords crystallographically characterised [PdCl(terpy*)]Cl and both O- and S-bound [Pd(SO3)(terpy*)]. The former is also available from [PdCl2(MeCN)n] (n = 0, 2) and terpy*; the latter from aerobic oxidation of [Pd(dba)2]–terpy*–SO2 mixtures (dba = dibenzylideneacetone). Oxidation of [Pd(SO3)(terpy*)] with O2 (at 210 °C in PhNO2) yields crystallographically characterised O-bound [Pd(SO4)(terpy*)]. The crystal structures of two related compounds are also reported: [Pd(OAc)(terpy*)]Cl and [PdCl2(bipy*)].

  4,4′,4″-三(叔丁基)-2,2′:6′,2″-吡啶-2-基（terpy*）与气态SO2–O2混合物及[PdCl2(MeCN)2]反应，经过水相后处理，得到结晶学表征的[PdCl(terpy*)]Cl和O键及S键结合的[Pd(SO3)(terpy*)]。前者也可以通过[PdCl2(MeCN)n]（n = 0, 2）和terpy*得到；后者则来自[Pd(dba)2]–terpy*–SO2混合物的好氧氧化（dba = 二苯亚甲基丙酮）。在210 °C下，使用O2氧化[Pd(SO3)(terpy*)]可获得结晶学表征的O键[Pd(SO4)(terpy*)]。还报道了两个相关化合物的晶体结构：[Pd(OAc)(terpy*)]Cl和[PdCl2(bipy*)]。
