Application

1,3-Bis(2,4,6-trimethylphenyl)-1,3-dihydro-2H-imidazol-2-ylidene (IMes) is a nucleophilic N-heterocyclic carbene (NHC) ligand.It can be used to synthesize: • IMes ligated-rhodium complex as a catalyst for the selective hydrogenation of substituted aryl and heteroaryl boronate esters to cis-substituted borylated cycloalkanes.• IMes/ruthenium complex (Cp*Ru(IMes)Cl)(Cp* =?5-C5Me3) as a catalyst for olefin ring closing metathesis reaction. IMes is also used as an ancillary ligand in Pd-catalyzed Suzuki-Miyaura cross-coupling reaction between aryl chlorides or aryl triflates and arylboronic acids.
