| 中文摘要 | four novel bridged-amidines h2l {1,4-r-1[c(=nr2)(nhr2)}(2) [r-1 =c6h4, r-2=2,6-(pr2c6h3)-pr-i (h2l1); =c6h4, r-2=2,6-me2c6h3 (h2l2); r-i =c6h10, r-2=2,6-(pr2c6h3)-pr-i (h2l3); r-i =c6h10, r-2= 2,6-me2c6h3 (h2l4)]} were synthesized in 65%-78% isolated yields by the condensation reaction of dicarboxylic acid with four equimolar amounts of amines in the presence of ppse at 180 degrees c. alkane elimination reaction of ln(ch2sime3)(3)(thf)(2) (ln=y. lu) with 0.5 equiv. of amidine in thf at room temperature afforded the corresponding bimetallic rare earth alkyl complexes (thf)(me3sich2)(2)lnl(1)ln(ch2sime3)(2)(thf) [lit = y (1), lu (2)1, (thf)(me3sich2),lnl(2)ln(ch2sime3)(2)(thf) [ln=y (3), lu (4)], (thf)(me3sich2)(2)(yly)-y-3(ch2s1me3)(2)(thf) (5), (thf)(me3sich2)(2)yl4-y(ch2sime3)(2)(thf) (6) in 72%-80% isolated yields. these neutral complexes showed activity towards l-lactide polymerization in toluene at 70 degrees c to give high molecular weight (m>10(4)) and narrow molecular weight distribution 1.40) polymers. |
