Abstract

Under light irradiation, a reaction of N‐(2‐(prop‐1‐en‐2‐yl)phenyl)benzamides, thianthrenium salts and sodium hydrogen sulfite under copper catalysis and photocatalysis is developed. Diverse sulfonated benzo[d][1,3]oxazines are generated in good yields with broad functional group tolerance by using sodium hydrogen sulfite as the sulfur dioxide surrogate. During the reaction process, a radical pathway with the insertion of sulfur dioxide is proposed.

硫铵盐和亚硫酸氢钠合成磺化苯并[d][1,3]恶嗪

在光催化和铜催化下，研究了N‐（2‐（prop‐1‐en‐2‐基）苯基）苯酰胺、硫铵盐和亚硫酸氢钠在光催化下的反应。以亚硫酸氢钠为二氧化硫替代品，产率高、官能团耐受性广，可合成多种磺化苯并[d][1,3]恶嗪。在反应过程中，提出了一种引入二氧化硫的自由基途径。

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.
