In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 53199-31-8, name is Bis(tri-tert-butylphosphine)palladium, introducing its new discovery. SDS of cas: 53199-31-8
Trifluoromethylthiolation of aryl iodides and bromides enabled by a bench-stable and easy-to-recover dinuclear palladium(I) catalyst
Abstract While 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 C-SCF3 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. Pd double team: The cross-coupling enabled by an air-, moisture-, and thermally stable dinuclear PdI complex was explored. Highly efficient C-SCF3 coupling of a range of aryl iodides and bromides was achieved and the catalyst was recovered by simple column chromatography, thus highlighting its robustness and the possibility for catalyst recycling. Kinetic and computational data support the feasibility of dinuclear PdI catalysis.
