Ketones substituted with an alkali metal. Isolation and some properties

With lithium, sodium, or potassium some derivatives of aliphatic ketones have been isolated. Their IR spectra in various media have been recorded, and in strongly solvating solvents confirm the enolate structures. The interaction of metalated 2,2-dimethyl-3-butanones with t-butoxides of the same alkali metal was demonstrated. Lithio-2,2-dimethyl-3-butanone reacted with alkoxides of heavier alkali metals via a metal—metal exchange reaction with formation of sodio- or potassio-2,2-dimethyl-3-butanone.
