Abstract
AbstractWhile palladium catalysis is ubiquitous in modern chemical research, the recovery of the active transition‐metal complex under routine laboratory applications is frequently challenging. Described herein is the concept of alternative cross‐coupling cycles with a more robust (air‐, moisture‐, and thermally‐stable) dinuclear PdI complex, thus avoiding the handling of sensitive Pd0 species or ligands. Highly efficient CSCF3 coupling of a range of aryl iodides and bromides was achieved, and the recovery of the PdI complex was accomplished via simple open‐atmosphere column chromatography. Kinetic and computational data support the feasibility of dinuclear PdI catalysis. A novel SCF3‐bridged PdI dimer was isolated, characterized by X‐ray crystallography, and verified to be a competent catalytic intermediate.
