Zusammenfassung:
A selective, nonchelation‐assisted methylation of arenes has been developed. The overall transformation, which combines a C−H functionalization reaction with a nickel‐catalyzed cross‐coupling, offers rapid access to methylated arenes with high para selectivity. The reaction is amenable to late‐stage methylation of small‐molecule pharmaceuticals.
