Abstract
1 2 3The 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).
