    • The invention relates to a method for producing organo alkali-metal compounds by reacting metal lithium, sodium or potassium with organic compounds containing at least one acidic 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 moles of the hydrogen acceptor are used per mole of acid hydrogen, which hydrogen can be replaced by lithium, sodium or potassium, whereby 1 to 3, moles of lithium, sodium or potassium are used per mole of acid hydrogen and the acid CH bond has a pKa value of 10 to 30. Cyclopentadiene, indene, fluorene and substitution products thereof, or monosubstituted alkynes or methane substitution products, are preferred CH acid organic compounds. Hydrocarbons used as hydrogen acceptors include these with at least one CC double bond in conjugation with either another CC double bond or with a monocyclic aryl radical.
    • 本发明涉及通过使金属锂,钠或钾与溶剂中至少含有一个酸性CH键的有机化合物反应制备有机碱金属化合物的方法。 本发明的方法的特征在于反应在氢受体的存在下进行,其中每摩尔酸氢使用0.5至5摩尔的氢受体,该氢可被锂,钠或钾代替,由此 1至3,每摩尔酸氢使用锂,钠或钾的摩尔数,酸性CH键的pKa值为10至30.环戊二烯,茚,芴及其取代产物,或单取代炔或甲烷取代产物, 是优选的CH酸有机化合物。 用作氢受体的碳氢化合物包括与另一个CC双键或单环芳基共轭的至少一个CC双键的那些。
