A new transient stabilization effect (TSE) of CO2 is identified and applied to the electrochemical hydrogenation of azo compounds and the reductive coupling of α-ketoesters. The TSE influence of CO2 means that overactive intermediates can be captured by CO2 to prevent their decomposition or side reaction to complete the synthesis that is difficult to achieve by direct means. The CO2 can be released
确定了 CO 2的新瞬态稳定效应 (TSE),并将其应用于偶氮化合物的电化学氢化和 α-酮酯的还原偶联。CO 2的TSE影响意味着过度活跃的中间体可以被CO 2捕获以防止其分解或副反应以完成难以通过直接方式实现的合成。CO 2可以稍后通过脱羧过程释放。

Sulfonic ester is a chemical structure common to many organic molecules, including biologically active compounds. Herein, a visible-light-induced synthetic method to prepare aryl sulfonic ester from arylazo sulfones was developed. In the present study, a one-pot reaction was carried out using arylazo sulfones, DABSO (DABCO·(SO2)2), and alcohols in the presence of CuI as a coupling catalyst and HCl
