Verfahren zur Herstellung von Organoalkalimetallverbindungen

摘要

The invention relates to a method for producing organoalkali-metal compounds by reacting metal lithium, sodium or potassium with an organic compound containing at least one acid CH bond in a solvent. The inventive method is characterized in that the reaction is carried out in the presence of a hydrogen acceptor, wherein 0.5 to 5 mols of the hydrogen acceptor are used per mol of acid hydrogen which can be replaced by lithium, sodium or potassium, whereby 1 to 3 mols of lithium, sodium or potassium are used per mol of acid hydrogen and the acid CH bond has a pka value of 10 to 30. Cyclopentadiene, indene, fluorene and substitution products thereof or mono-substituted alkynes or methane substitution products are used CH acid organic compounds. Hydrocarbons are used as hydrogen acceptors with at least one CC double bond, which are in conjugation with either another CC double bond or with a monocyclic aryl radical.
