Abstract
A method has been developed for the synthesis of symmetrical and unsymmetrical aryl 1, 2‐diketones at room temperature, without the need for transition metals or photocatalysts. This protocol employs aromatic terminal alkynes or alkenes to react with aryl iodides under conditions involving formate, air, and DMSO. Mechanistic studies indicate that formate, air, and DMSO are all necessary conditions, and that the highly reactive carbon dioxide radical anion (CO2•−) generated under these conditions plays a key role in the reaction.
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.
