(SP-4-1)-[1,3-Bis[2,6-bis(1-methylethyl)phenyl]-1,3-dihydro-2H-imidazol-2-ylidene]dichloro(1-methyl-1H-imidazole-κN3)palladium is a sterically shielded palladium(II) complex featuring a bulky N-heterocyclic carbene ligand. The electron-rich carbene moiety enhances stability and facilitates oxidative addition under standard conditions. This robust catalyst enables efficient cross-coupling reactions in demanding synthetic transformations.
(SP-4-1)-[1,3-Bis[2,6-bis(1-methylethyl)phenyl]-1,3-dihydro-2H-imidazol-2-ylidene]dichloro(1-methyl-1H-imidazole-κN3)palladium serves as a robust, bench-stable precatalyst for palladium-catalyzed cross-coupling reactions. Its sterically encumbered N-heterocyclic carbene ligand enhances catalyst longevity and tolerates diverse functional groups, enabling efficient C–C and C–heteroatom bond formation under standard reaction conditions. Ideal for Suzuki-Miyaura, Negishi, and Stille couplings, it facilitates high yields with minimal metal leaching, supporting scalable synthesis and streamlined purification workflows.
