Name: 3-(Trifluoromethyl)-1H-pyrazoleIn 2015 ,《Synthesis, characterization, and ethylene polymerization behavior of Cr(III) catalysts based on bis(pyrazolylmethyl)pyridine and its derivatives》 appeared in Journal of Molecular Catalysis A: Chemical. The author of the article were Woo, Jeong Oh; Kang, Sung Kwon; Park, Jong-Eun; Son, Kyung-sun. The article conveys some information:
New chromium(III) [Cr(III)] catalysts based on 2,6-bis(1-pyrazolylmethyl)pyridine derivatives have been synthesized, characterized, and evaluated for ethylene polymerization All ligands with substituents on the pyrazole rings were analyzed by single-crystal X-ray diffraction to clearly identify isomer structures. Addnl., X-ray analyses of a new Cr(III) complex bearing 2,6-bis[(4,5-dimethyl-1H-pyrazol-1-yl)methyl]pyridine showed tridentate coordination on the mer-octahedral chromium sphere. Upon activation with dry Me aluminoxane, the precatalysts produce polyethylene (PE) as a major product, and their catalytic performances were affected by the substituents on the pyrazole units; the introduction of functional groups on the pyrazole compositions and the mol. weight of the PE. The experimental process involved the reaction of 3-(Trifluoromethyl)-1H-pyrazole(cas: 20154-03-4Name: 3-(Trifluoromethyl)-1H-pyrazole)
3-(Trifluoromethyl)-1H-pyrazole(cas: 20154-03-4) belongs to pyrazoles. Pyrazole derivatives have been reported to exhibit a wide range of applications in medicinal chemistry and pharmacology. A large number of drugs incorporating pyrazole structure have been utilized as partial agonists for nicotinic acid receptors, antidepressants, antimicrobial agents, antiviral agents, and antifungal agents solely or along with the combination of other structural motifs.Name: 3-(Trifluoromethyl)-1H-pyrazole
