Abstract

We report synthesis of N-heterocyclic carbenes (NHCs), N,N'-bis{2,6-bis(3,5-dialkylphenyl)methy-4-methoxyphenyl}imidazol-2-ylidenes {alkyl = ethyl (L2) or n-propyl (L3)} and their applications to nickel-catalyzed C–H alkylation reactions of arenes. They showed site-selectivities and/or yields higher than NHCs used previously for the reactions.
