| 英文摘要 | (e)-1-(4-methylphenyl)-1,3-butadiene (e-1-mpbd) synthesized via the wittig-type reaction was polymerized with the ternary catalytic system (flu-nhc)lu(ch2sime3)(2)/alibu(3)/[ph3c][b(c6f5)(4)] (flu-nhc = c13h8ch2ch2(nchchn(c6h2me3-2,4,6)c) to afford a new product containing exclusively trans-3,4 (>99%) units with perfect syndiotacticity (rrrr > 99%). the regio-3,4 tacticity was proved by the ir and nmr (h-1 and c-13) spectroscopic analyses, while the 3,4-stereotacticity was confirmed by a model polymer with lower regularity (3,4 = 90.9%, rrrr = 49.3%) prepared by the binary catalytic system (am-nhc)lu(ch2sime3)(2)/[ph3c][b(c6f5)(4)] (am-nhc = 2,6-(prc6h3n)-pr-i-c(c6h5)nch2ch2(nchchn(c6h2me3-2,4,6)c). the trans-planar conformation was uncovered through 2d-noesy and c-13 cpmas nmr technologies. this represents the first stereo 3,4-syndioselective polymerization of 1,3-dienes achieved by a rare-earth metal based catalyst. moreover, hydrogenating the resulting polymer gave the highly syndiotactic poly(4-methylphenyl-1-butene), which cannot be achieved by any other manner at the present stage. |
