Palladium‐Catalyzed Cross‐Coupling of Transiently Stable Heterocyclic Organolithiums

Angewandte Chemie, EarlyView.
Fast coupling outcompetes organolithium decomposition. Catalyst benchmarking enables transient pyridyl, quinolyl, indazolyl, and related organolithiums to participate in the Murahashi coupling, while continuous‐flow generation extends the approach to reagents too unstable for conventional batch handling.
