Modern transition-metal-catalyzed reactions have been shown to be of indispensable value for organic synthesis.[1] In particular, the cross-coupling of alkyl halides, including problematic unactivated alkyl halides, have now emerged as promising candidates to complement and extend the scope of the traditional Friedel–Crafts alkylation.[2, 3] The incorporation of a new alkyl chain on an aromatic moiety often proceeds by the metal- ...
