Abstract Exchange reactions at ambient temperature in the dark between symmetrical aryl thiosulfinates Ar-S(O)-S-Ar are described. A polar mechanism involving a four-center transition state is proposed for the reaction, supported by the ease of fission of the S-S bond with the polarity introduced by the sulfinyl group. The thiosulfinate exchanges demonstrate a reaction common to a series of thioesters
摘要 描述了对称芳基硫代亚磺酸盐 Ar-S(O)-S-Ar 之间在室温下在黑暗中的交换反应。该反应提出了一种涉及四中心过渡态的极性机制,这得到了 SS 键与亚磺酰基引入的极性的容易裂变的支持。硫代亚磺酸盐交换证明了一系列硫酯(二硫化物/硫代亚磺酸盐)和它们的酰胺(次磺酰胺/亚磺酰胺)的共同反应,它们的硫原子的氧化水平不同,但在与官能团类型相关的条件下。
