Product Details of 258278-25-0On September 13, 2021 ,《Synthesis of L-Au(I)-CF2H Complexes and Their Application as Transmetalation Shuttles to the Difluoromethylation of Aryl Iodides》 was published in Organometallics. The article was written by Garcia-Dominguez, Patricia. The article contains the following contents:
We describe herein two alternative protocols to efficiently prepare difluoromethylgold(I) complexes bearing ancillary ligands with different electronic and steric properties. LAu-OX (X = H and t-Bu) species, formed in the presence of base, have been identified as intermediate complexes involved in these transformations. The application of these compounds as “”CF2H transmetalation shuttles”” from gold to palladium has been demonstrated in a Pd-catalyzed difluoromethylation reaction of aryl iodides, in which the Au-to-Pd transfer of “”CF2H”” is feasible under stoichiometric conditions. These findings will pave the way for catalytic manifolds in gold chem. The experimental part of the paper was very detailed, including the reaction process of 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride(cas: 258278-25-0Product Details of 258278-25-0)
1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride(cas: 258278-25-0) may be used as a precursor to the free carbene 1,3-bis(2,6-diisopropylphenyl)-2-imidazolidinylidene, and also used as an in situ formed catalyst in a variety of reactions, e.g. amination, Heck coupling reaction, the ring-opening metathesis polymerization (ROMP), hydrogenation.Product Details of 258278-25-0In addition, it can efficiently catalyze the Suzuki-Miyaura coupling of aryl chlorides with aryl boronic acids.
