1,3-Bis(2,4,6-trimethylphenyl)imidazol-2-ylidene, min. 98%

Application

1,3-Bis(2,4,6-trimethylphenyl)imidazol-2-ylidene, min. 98%, serves as a highly effective nucleophilic N-heterocyclic carbene (NHC) ligand. Its primary purpose is to facilitate the synthesis of various metal complexes that act as catalysts in key chemical reactions. Specifically, it enables the creation of a rhodium complex for the selective hydrogenation of substituted aryl and heteroaryl boronate esters into cis-substituted borylated cycloalkanes. Additionally, this product is utilized in forming a ruthenium complex, which acts as a catalyst in olefin ring-closing metathesis reactions, demonstrating enhanced reactivity. It also plays a crucial role as an ancillary ligand in palladium-catalyzed Suzuki-Miyaura cross-coupling reactions, particularly between aryl chlorides or aryl triflates and arylboronic acids. This nucleophilic carbene serves as a bulky, electron-rich "phosphine mimic," optimizing performance in metal-catalyzed reactions.
