애플리케이션
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 is also used as an ancillary ligand in Pd-catalyzed Suzuki-Miyaura cross-coupling reaction between aryl chlorides or aryl triflates and arylboronic acids.
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* =η5-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.

In the search of smarter routes to control the conditions of N-heterocyclic carbene (NHCs) formation, a two-component air-stable NHC photogenerating system is reported. It relies on the irradiation at 365 nm of a mixture of 2-isopropylthioxanthone (ITX) with 1,3-bis(mesityl)imidazoli(ni)um tetraphenylborate. The
