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.

甲酸-空气-二甲基亚砜条件下，可见光-光催化催化末端炔/烯烃和芳基卤化物不对称合成二芳基1,2 -二酮

本文提出了一种在室温下合成对称和不对称芳基1,2 -二酮的方法，无需过渡金属或光催化剂。本协议采用芳香末端炔或烯烃与芳基碘化物在甲酸盐、空气和二甲基亚砜的条件下反应。机理研究表明甲酸盐、空气和DMSO都是反应的必要条件，而在这些条件下产生的高活性二氧化碳自由基阴离子（CO2•−）在反应中起着关键作用。

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.
