The reaction of alkali (Li, Na, K, and Cs) and tetrabutylammonium salts of fluorene and of lithium salt of 9-phenylfluorene with cyclohexanone was studied in dimethoxyethane, ether, benzene, and hexamethylphosphorotriamide.The reaction proceeds to give both addition and enolization.The reaction is an equilibrium process as shown by a study of the reverse reactions: decomposition of the alcoholate and the reactions of the alkaline enolates of cyclohexanone with fluorene.The position of the equilibrium is very sensitive to the nature of the cation and the solvent and the carbanion structure.The possible causes for this effect are considered.
