A direct and convenient method for the C-H arylation and alkylation of electron-deficient N-heteroarenes with readily available organozinc reagents has been developed. This transformation could be readily performed in the absence of a transition-metal catalyst and external oxidants, affording a wide range of substituted heteroarenes with good functional group tolerance in good to excellent yields. The developed simple protocol is scalable to the gram level and suitable for late-stage modification of bioactive molecules and drugs.

Despite significant advances in the catalytic direct arylation of heteroarenes, the application of this reaction to pyridines has been met with limited success. An oxidative nucleophilic arylation strategy has been developed to overcome this problem. Pyridine, pyrazine, quinolone, and related electron-deficient N-heteroarenes can be arylated at the most electrophilic site using the developed nickel-catalyzed reaction. This protocol serves as a complementary method to catalytic direct arylation reactions. Less is more: Pyridine, pyrazine, quinoline and related electron-deficient N-heteroarenes can be arylated at the most electrophilic site using organozinc reagents through nickel catalysis. This protocol serves as a complementary method to catalytic direct arylation reactions. Copyright
