We have developed an electrochemical method for the direct C–H sulfonylation of aldehyde hydrazones using sodium sufinates as the sulfonylating agent under supporting electrolyte-free conditions. This straightforward sulfonylation strategy afforded a library of (E)-sufonylated hydrazones with high tolerance of various functional groups. The radical pathway of this reaction has been revealed by the
我们开发了一种电化学方法,用于在无支持电解质条件下使用亚磺酸钠作为磺酰化剂对醛腙进行直接 C-H 磺酰化。这种直接的磺酰化策略提供了一个对各种官能团具有高耐受性的 ( E )-磺酰化腙库。机理研究揭示了该反应的激进途径。
