  磺酰肼电化学合成亚磺酸酯和磺酸酯

  摘要：

  开发了一种由磺酰肼合成亚磺酸酯和磺酸酯的电化学合成方法。在DMF溶剂中，5 mA恒电流下，用原甲酸三烷基酯处理磺酰肼，然后优化反应条件，合成烷基亚磺酸酯。相反，当反应在烷基醇溶剂中以15mA的恒定电流进行时，仅获得烷基磺酸酯。各种取代的芳基磺酰肼提供了中等至良好产率的所需亚磺酸酯和磺酸酯。机理研究表明，磺酰基自由基是通过电化学氧化形成的，并且它们与烷基自由基或烷氧基自由基反应生成各自的酯产物。

  The kinetics of the reactions between trimethyloxonium hexafluorophosphate and a series of tetra-n-butylammonium arenesulfonates have been studied in acetonitrile at −23.4°. With the oxonium salt concentration at about 0.01 M, two series of runs were carried out; Hammett plots of the second-order rate coefficients led to ϱ values of −1.18±0.04 for 0.04 M arenesulfonate salt and −1.07±0.02 for 0.16

  日期：——

  Methyl, ethyl, and isopropyl esters of six alkanesulfonic acids and five p-substituted benzenesulfonic acids were synthesized and their alkylating abilities were evaluated in terms of the chemoselectivity toward 4-(p-nitrobenzyl) pyridine (NBP) in phosphate buffer (pH 6.0) containing 60% acetone. The chemoselectivity constant toward NBP, SNBP, was defined as the logarithm of the ratio of the molar fraction of an alkylating sulfonate which is consumed for alkylation of NBP versus the molar fraction of the residual alkylating agent which is hydrolyzed in the buffer medium. It was found that SNBP was not only markedly dependent on the structure of the alkyl moiety of the molecule, but also appreciably dependent on the electronic nature of the leaving sulfonic acid moiety. The structure-chemoselectivity relationship is discussed.

  合成了六种烷基磺酸和五种对取代苯磺酸的甲基、乙基和异丙基酯，并评估了它们在含有60%丙酮的磷酸盐缓冲液（pH 6.0）中对4-(对硝基苄基)吡啶（NBP）的烷基化能力。对NBP的化学选择性常数SNBP被定义为用于NBP烷基化的烷基磺酸的摩尔分数与在缓冲介质中水解的剩余烷基化试剂的摩尔分数之比的对数。研究发现，SNBP不仅显著依赖于分子中烷基部分的结构，还明显依赖于离去的磺酸部分的电子性质。讨论了结构与化学选择性之间的关系。
