In the presence of a nickel catalyst, 1,3‐butadiene undergoes selective dimerization and alkylarylation with alkyl fluorides and aryl Grignard reagents to give 1,6‐octadienes with alkyl and aryl groups at the 3‐ and 8‐positions, respectively, by the consecutive formation of three carbon–carbon bonds. The formation of an anionic nickel complex plays an important role in forming C−C bonds with alkyl...
Starke C‐F‐Bindungen wurden mit einem anionischen Nickelkatalysator durchtrennt, um die Alkylketten der Alkylfluoride in die gewünschten Kupplungsprodukte einzubauen. In der Zuschrift auf S. 5640 ff. beschreiben N. Kambe, T. Iwasaki et al. eine nickelkatalysierte regio‐ und stereoselektive Mehrkomponentenreaktion von Alkylfluoriden, Aryl‐Grignard‐Reagentien und zwei Molekülen 1,3‐Butadien, die durch...
