Halide-bridged 1- and 2-methylnaphthyl palladium dimers are presented as convenient, yet highly efficient palladium sources for cross-coupling catalysis. The bench-stable complexes smoothly react with various ligands yielding monoligated palladium precatalysts. These display record-setting activity in various catalytic reactions, clearly beyond that achievable by ligand screening alone.

Sodium hydride (NaH) is widely used as a Brønsted base in chemical synthesis and reacts with various Brønsted acids, whereas it rarely behaves as a reducing reagent through delivery of the hydride to polar π electrophiles. This study presents a series of reduction reactions of nitriles, amides, and imines as enabled by NaH in the presence of LiI or NaI. This remarkably simple protocol endows NaH with

Recent developments in controlled C–H functionalization transformations continue to inspire new retrosynthetic disconnections. One tactic in C–H functionalization is the intermolecular C–H insertion reaction of rhodium-bound carbenes. These intermediates can undergo highly selective transformations through the modulation of the ligand framework of the rhodium catalyst. This work describes our continued
