The invention relates to a method for binding heteroatom-carbon bonds. According to said method, a lithium compound (II) is first generated by reacting aliphatic or aromatic halogen compounds (I) with lithium metal, said compound is then used for the deprotonation of the compounds (III) or (V). The lithium salts of formulas (IV) or (VI) obtained by said deprotonation are subsequently reacted with suitable carbon electrophiles (equation I), said process binding the heteroatom-carbon bond and forming the products (VIII) or (VIII), (equation I).
本发明涉及一种结合杂原子-碳键的方法。根据该方法,首先通过将脂肪族或芳香族卤代化合物(I)与锂金属反应生成锂化合物(II),然后使用该化合物去质子化化合物(III)或(V)。随后,通过适当的碳亲电体(方程式I)反应获得由去质子化得到的公式(IV)或(VI)的锂盐,该过程结合了杂原子-碳键并形成了产物(VIII)或(VIII)(方程式I)。
