《Rapid and mild synthesis of Au-NHC complexes in a simple two-phase flow reactor》 was published in Dalton Transactions in 2021. These research results belong to Jonsson, Helgi Freyr; Fiksdahl, Anne; Harvie, Andrew J.. Name: 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride The article mentions the following:
We describe a simple two-phase flow reactor which allows for the rapid synthesis of several Au(I)-NHC complexes in high yields (>88%), under mild conditions, and with minimal workup. Translation of the standard weak base method to a two-phase flow reaction prevents the common problem of decomposition to Au(0). The reaction can be scaled up more than ten-fold without loss in conversion efficiency. An optional second stage allows for direct synthesis of Au(III)-NHC complexes, without isolation of the Au(I)-NHC intermediate, with a two-step isolated yield of 82%. After reading the article, we found that the author used 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride(cas: 258278-25-0Name: 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride)
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.Name: 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chlorideIn addition, it can efficiently catalyze the Suzuki-Miyaura coupling of aryl chlorides with aryl boronic acids.
