Formation and Characterization of Gaseous Adducts of Carbon Dioxide to Magnesium, (CO2)MgX− (X=OH, Cl, Br)

This is the authors' abstract. We don't add key points for this paper.

A good fix: the structure and chemical reactivity of a reduced form of CO(2) bonded to magnesium, XMg(η(2)-O(2)C)(-), is reported. Upon reaction with water it loses CO, while it adds CH(3) upon reaction with alkyl halides, thereby signifying nucleophilicity of the carbon atom in XMg(η(2)-O(2)C)(-) in S(N)2 reactions.
