Group II metals alkoxides

The reactions are usually carried out by adding the halo ketone to a solution or suspension of the base in either a protic solvent (water, alcohols) or an ether (diethyl ether, dioxane, dimethoxyethane). The bases employed include hydroxides of Group I and Group II metals alkoxides, carbonates and hydrogen-carbonates of Group I metals ammonia, and amines. There is no one recommended set of experimental conditions, because both the mechanism of the reactions and the type of products obtained depend upon the initial choice of a-halo ketones. In addition, since the halo ketones are highly reactive molecules, side products are inevitably obtained those most commonly produced are shown in Scheme...
