In 2022,Cao, Lixin; Cai, Zhengguo; Li, Mingyuan published an article in Macromolecules (Washington, DC, United States). The title of the article was 《Phosphinobenzenamine Nickel Catalyzed Efficient Copolymerization of Methyl Acrylate with Ethylene and Norbornene》.Related Products of 7073-94-1 The author mentioned the following in the article:
A series of phosphinobenzenamine-based nickel complexes bearing substituted phenylphosphine ligands were synthesized and characterized. These nickel complexes combined with methylaluminoxane (MAO) exhibited very high activity (~106 g mol-1 h-1) and good thermal stability for norbornene polymerization The nickel catalysts were able to conduct copolymerization of norbornene and Me acrylate (MA) with high activity (3.76 x 105 g mol-1 h-1) to give high-mol.-weight functionalized cyclic olefin copolymer (COC) with reasonable MA incorporation (2.39-6.47 mol %). Moreover, the nickel catalysts also promote the copolymerization of ethylene and MA with moderate activity (~104 g mol-1 h-1) to produce semicrystalline high-mol.-weight polar functionalized polyethylene (PE). The MA incorporation in the copolymer was controlled in a wide range (up to 15.5 mol %). These complexes without any sterically bulky substituent on the ligand are distinctive examples of earth-abundant nickel complexes toward the direct copolymerization of ethylene or norbornene with the challenging vinyl polar monomer MA. The results came from multiple reactions, including the reaction of 1-Bromo-2-isopropylbenzene(cas: 7073-94-1Related Products of 7073-94-1)
1-Bromo-2-isopropylbenzene(cas: 7073-94-1) belongs to organobromine compounds.Most of the natural organobromine compounds are produced by marine organisms , and several brominated metabolites with antibacterial , antitumor , antiviral , and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others.
