W. published an article.Recommanded Product: 1H-Imidazolium, 1,3-bis[4-iodo-2,6-bis(1-methylethyl)phenyl]-, chloride (1:1) The title of the article was Synthesis of Pd Complexes Containing Tailed NHC Ligands and Their Use in a Semicontinuous Membrane-Assisted Suzuki Cross-Coupling Process. And the article contained the following:

Homogeneous catalysis has proved to be a reliable method for preparing numerous mol. entities, but catalysts can be expensive and difficult to remove. Because of this, industry targets catalysts that are easily separated and recovered and feature increased turnover numbers The ongoing shift from multipurpose batch reactors toward continuous manufacturing in fine chems. synthesis results in a new set of catalyst requirements. This paper reports the design and use of Pd complexes suitable for a semicontinuous Suzuki cross-coupling reaction based on a membrane-assisted reactor. These Pd complexes contain tailed N-heterocyclic carbene (NHC) ligands, allowing internal catalyst recovery by organic solvent nanofiltration with top-layer-modified ceramic membranes. These membranes give selective nanofiltration of the catalyst based on a combination of size exclusion and affinity separation (solvent-solute-membrane interactions). The semicontinuous system developed led to significantly improved turnover numbers, simplified product isolation, and consequently reduced mass intensity by simply adding more of the reactants and reagents to the reaction vessel. The experimental process involved the reaction of 1H-Imidazolium, 1,3-bis[4-iodo-2,6-bis(1-methylethyl)phenyl]-, chloride (1:1)(cas: 934008-48-7).Recommanded Product: 1H-Imidazolium, 1,3-bis[4-iodo-2,6-bis(1-methylethyl)phenyl]-, chloride (1:1)

Wang, Chang-An; Li, Yan-Wei; Hou, Xian-Ming; Han, Yin-Feng; Nie, Kun; Zhang, Jian-Ping published an article in 2016, the title of the article was N-Heterocyclic Carbene-based Microporous Organic Polymer Supported Palladium Catalyst for Carbon-Carbon Coupling Reaction.SDS of cas: 934008-48-7 And the article contains the following content:

Highly dispersed Pd(0) nanoparticles were successfully immobilized into stable N-heterocyclic carbene-based microporous organic polymer (NHC-MOP) via a simple post-treatment. The microporous structure of the NHC-MOP polymer can efficiently prevent the aggregation of Pd nanoparticles and the NHC-MOP network embedding with N-heterocyclic carbene ligand can efficiently disperse Pd particles, which promoting the catalytic activity of the polymers. As-synthesized Pd@NHC-MOP catalyst shows excellent catalytic activity in catalyzing the Suzuki-Miyaura and Heck cross-coupling reactions. The superior utility of Pd@NHC-MOP in catalysis was elucidated by the broad scope of the reactants and the high yields of the reaction products, together with the high recyclability of the catalyst. The Pd@NHC-MOP catalyst can be reused at least eleven times for Suzuki-Miyaura coupling reaction or nine times for Heck coupling reaction without any significant loss of the catalytic activity.
