Air and water-persistent C-centered radical anion based on FLP-activated CO2
<div> Organic radicals play pivotal roles across chemistry, biology, and materials science. Although typically short-lived and highly reactive, considerable efforts have been devoted to stabilizing open-shell molecules to better understand their properties and expand their applications. Among them, air-persistent organic radicals (AOPRs) stand out as benchmarks of stability. Herein, we report the first air-and water-persistent radical anion derived from CO2. This species is generated from an FLP-activated CO2 adduct comprising an Nheterocyclic carbene (NHC) as the Lewis base and a ditopic perfluorinated diborane as the Lewis acid. Combined experimental and theoretical studies reveal that both thermodynamic and kinetic factors contribute to the remarkable stability of this open-shell system. </div>
