Okuyama, Tadashi published the artcileSubstituent effects in the benzofuran system. III. Cationic polymerization, Recommanded Product: 6-Methoxybenzofuran, the main research area is benzofuran polymerization substituent effect.
Cationic copolymerization of pairs of benzofuran derivatives have been carried out in CH2Cl2 using SnCl4-CCl3CO2H (2:1) as catalyst at 0°. Effects of 2- and 3-Me substitutions on the monomer reactivity ratio suggested that the polymeric cation added at the 2-C of benzofuran. Anal. of the effects of 5- and 6-substituents on the reactivity revealed that the transmission efficiency of electronic effects through the two paths, the bonds 8-3 and 9-1-2, was comparable in magnitude. The transition state of the propagation step resembled a bridged carbonium ion intermediate.
Bulletin of the Chemical Society of Japan published new progress about Polymerization. 50551-63-8 belongs to class benzofurans, name is 6-Methoxybenzofuran, and the molecular formula is C9H8O2, Recommanded Product: 6-Methoxybenzofuran.
