Soluble, crystalline, and thermally stable alkali CO₂ ^- and carbonite (CO₂ ^2-) clusters supported by cyclic(alkyl)(amino) carbenes.

ABSTRACT: The mono- and dianions of CO₂ (i.e., CO₂ ^- and CO₂ ^2-) have been studied for decades as both fundamentally important oxycarbanions (anions containing only C and O atoms) and as critical species in CO₂ reduction and fixation chemistry. However, CO₂ anions are highly unstable and difficult to study. As such, examples of stable compounds containing these ions are extremely limited; the unadulterated alkali salts of CO₂ (i.e., MCO₂, M₂CO₂, M = alkali metal) decompose rapidly above 15 K, for example. Herein we report the chemical reduction of a cyclic (alkyl)(amino) carbene (CAAC) adduct of CO₂ at room temperature by alkali metals, which results in th
