摘要

甲基硫基的生产通常依赖于气态甲硫醇或二甲基二硫化物。本文提出了一种由甲基硫代磷盐光生成甲基硫代自由基的新方法，通过电荷转移配合物策略合成甲基硫代噻吩苯基。在这种方法中，甲基硫代膦盐作为电子受体，而2-异氰酸双芳基作为电子给体。该策略的特点是其条件和操作简单，并且可以扩展到生成各种烷基（芳基）硫自由基。

Photoinduced Methylthio Radical Generation from Methylthiophosphonium Salt

The production of methylthio radical typically relies on gaseous methanethiol or dimethyl disulfide. Herein, we present a new and straightforward method for the photogeneration of methylthio radical from methylthiophosphonium salt, enabling the synthesis of methylthiophenanthridines via charge transfer complex strategy. In this approach, the methylthiophosphonium salt acts as the electron acceptor, while 2-isocyanobiaryls serve as the electron donors. This strategy is distinguished by its simplicity in both conditions and operation, and can be extended for the generation of various alkyl(aryl)thio radicals.

期刊介绍： Advanced Synthesis & Catalysis (ASC) is the leading primary journal in organic, organometallic, and applied chemistry. The high impact of ASC can be attributed to the unique focus of the journal, which publishes exciting new results from academic and industrial labs on efficient, practical, and environmentally friendly organic synthesis. While homogeneous, heterogeneous, organic, and enzyme catalysis are key technologies to achieve green synthesis, significant contributions to the same goal by synthesis design, reaction techniques, flow chemistry, and continuous processing, multiphase catalysis, green solvents, catalyst immobilization, and recycling, separation science, and process development are also featured in ASC. The Aims and Scope can be found in the Notice to Authors or on the first page of the table of contents in every issue.
