Li-enolates are readily converted to Mn-enolates by treatment with manganese halides. In THF, the reaction is easily and economically performed with manganese chloride at room temperature. Mn-enolates can then be regioselectively monoalkylated in good yields. The formation of di and polyalkylated products is never observed (< 1%).
