revised on 10.05.2021, 00:05 and posted on 11.05.2021, 07:50 by Youngsuk Kim, Jung Eun Byeon, Gu Yoon Jeong, Seoung Su Kim, Hayoung Song, Eunsung Lee
The present manuscript describes the design, synthesis, and characterization of the most stable organic radical reported up to date.

Here we report:
▪ Synthesis and full characterization including X-ray structure of stable 1,2-dicarbonyl radicals
▪ Proposed mechanism for the formation of the presented radicals
▪ Redox reactivity of the radicals
▪ Stability of the radicals under various organic and inorganic conditions
