The author of 《Ruthenium-Catalyzed Alternating Ring-Opening Metathesis Copolymerization of Norborn-2-ene with Cyclic Olefins》 were Paradiso, Veronica; Grisi, Fabia. And the article was published in Advanced Synthesis & Catalysis in 2019. Safety of 1-Bromo-2-isopropylbenzene The author mentioned the following in the article:
A Grubbs-type olefin metathesis catalyst bearing a backbone-substituted unsym. N-heterocyclic carbene (NHC) ligand has been prepared from readily available reagents using a four-step synthetic protocol. This catalyst was found able to promote the alternating ring-opening metathesis copolymerization of norborn-2-ene (NBE) with cis-cyclooctene (COE) or cyclopentene (CPE) with a high degree of chemoselectivity (98% and 95% of alternating diads, resp.) at low comonomers ratios. The results came from multiple reactions, including the reaction of 1-Bromo-2-isopropylbenzene(cas: 7073-94-1Safety of 1-Bromo-2-isopropylbenzene)
1-Bromo-2-isopropylbenzene(cas: 7073-94-1) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals.Safety of 1-Bromo-2-isopropylbenzene The most pervasive is the naturally produced bromomethane.
