英文摘要 | a series of amidino n-heterocyclic carbene ligand supported rare-earth metal bis(alkyl) complexes (2,6-(r2c6h3n)-c-1=(crnch2ch2)-n-2(nchchn(c6h2me3-2,4,6)c))ln(ch2sime3)(2) [r-1 = pr-i, r-2 = ph, ln = lu (1a); r-1 = pr-i, r-2 = ph, ln = sc (1b); r-1 = ipr, r-2 = bu-t, ln = lu (2a); r-1 = me, r-2 = ph, ln = lu (3a)] were synthesized and characterized by nmr spectroscopy. on activation with [(ph3c)][(b(c6f5)(4))], complexes 1a, 2a and 3a exhibited high activities and high 3,4-selectivities (96.9%) for the polymerization of 2-phenyl-1,3-butadiene in a living mode to afford new plastic polydienes with high glass-transition temperatures (44.3-56.1 degrees c). the 3,4-selectivity decreased with increasing the polymerization temperature (25-60 degrees c), but increased with polarity of polymerization solvent in the order of chlorobenzene > toluene > cyclohexane. in contrast, complex 1b was almost inert for the polymerization of 2-phenyl-1,3-butadiene owing to its steric bulkiness. |
