In 2017,Rodriguez Castanon, Jesus; Sano, Natsuhiro; Shiotsuki, Masashi; Sanda, Fumio published 《Synthesis of poly(1-chloro-2-arylacetylene)s with high cis-content and examination of their absorption/emission properties》.Journal of Polymer Science, Part A: Polymer Chemistry published the findings.Safety of 1-Bromo-2-isopropylbenzene The information in the text is summarized as follows:
A series of 1-chloro-2-arylacetylenes [Cl-CC-Ar, Ar = C6H5 (1), C6H4-p-iPr (2), C6H4-p-OiPr (3), C6H4-p-NHC(O)OtBu (4), and C6H4-o-iPr (5)] were polymerized using (tBu3P)PdMeCl/silver trifluoromethanesulfonate (AgOTf) and MoCl5/SnBu4 catalysts. The corresponding polymers [poly(1)-poly(5)] with weight-average mol. weights of 6500-690,000 were obtained in 10-91% yields. THF-insoluble parts, presumably high-mol. weight polymers, were formed together with THF-soluble polymers by the Pd-catalyzed polymerization The Pd catalyst polymerized nonpolar monomers 1 and 2 to give the polymers in yields lower than the Mo catalyst, while the Pd catalyst polymerized polar monomers 3 and 4 to give the corresponding polymers in higher yields. The 1H NMR and UV-vis absorption spectra of the polymers indicated that the cis-contents of the Pd-based polymers were higher than those of the Mo-based polymers, and the conjugation length of the Pd-based polymers was shorter than that of the Mo-based polymers. Pd-based poly(5) emitted fluorescence most strongly among poly(1)-poly(5). © 2016 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.Chem. 2016. In the experiment, the researchers used 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.The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. Safety of 1-Bromo-2-isopropylbenzene The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.
