Unusual thermal stability of [Ru(bpy)₂(CO)(η¹-CO₂)] (1) as a metal-η¹-CO₂ complex was examined both in solid state and in solution. Compound 1 dissolves in CH₃CN containing LiCF₃SO₃. Interaction between Li⁺ and the η¹-CO₂ group enhances an electron flow from Ru to the CO₂ ligand and greatly contributes to the stabilization of the Ru-η¹-CO₂ bond. The reaction of [Ru(bpy)₂(CO)₂](PF₆)₂ with [Crown·K]₂CO₃ in dry CH₃CN selectively produced 1 through the 1:1 adduct with the RuC(O)-OCO₂ moiety. Stoichimetric formation of 1 from the 1:1 adduct is also assisted by [Crown·K]⁺ as a Lewis acid. Similarly, the reaction of [Ru(bpy)₂(CO)₂](PF₆)₂ with (Me₄N)₂CO₃ in DMSO gave the 1:1 adduct in the initial stage, which gradually changed to a metalloanhydride complex, [Ru(bpy)₂(CO)((CO)₂O)] due to the absence of Lewis acids to stabilize 1, since an addition of LiCF₃SO₃ to the solution gave [Ru(bpy)₂(CO)(η¹-CO₂)] quantitatively.
