  摘要：

  摘要新型的硼烷素B [（Oo-ArCH2）3-nN（CH2CH2O）n]（Ar = 2,4-di-MeC6H2; n = 0，1; n = 1，2; n = 2，3）具有以下特征通过B（OMe）3与一系列四齿配体如（HO-o- ArCH2）3-nN（CH2CHOH）n（Ar = 2,4-di-MeC6H2; n = 0，L1H3; n = 1，L2H3; n = 2，L3H3）。通过溶液1H，13C {1H}和11B NMR对化合物1-3进行了表征，并通过单晶X射线衍射确定了化合物1和3的晶体结构。化合物1和3是第一个在结构上表征的硼烷烃衍生物，分别在atrane笼中带有所有六元环和混合环系统。特别是1的分子结构表明其跨环NB键长度为1。

  (Pentamethylcyclopentadienyl)titanatranes, Cp*Ti(O-2,4-Me2C6H2-6-CH2)(n)N(CH2CH2O)(3-n)} (n = 0, 1; n = 1, 2; n = 2, 3), featuring three five-membered chelating rings (1) to two six-membered chelating rings (3) in a stepwise fashion through 2 were synthesized from the corresponding tri-hydroxy chelating ligands 1L-3L, respectively, using Cp*TiCl3 and triethylamine. Cp*Ti(O-2-C6H4)(3)N} (4) having three five-membered chelating rings from fully deprotonated N(C6H4-2-OH)(3) (4L) was also synthesized. Xray analysis shows that 2 and 4 have slightly distorted trigonal bipyramidal geometry around Ti. These compounds exhibited good catalytic activity for the syndiospecific polymerization of styrene in the presence of MAO at various polymerization conditions. (C) 2008 Elsevier B. V.

  The new titanatranes ArOTioO(o-Ar'CH2)(3-x)N(CH2CH2O)(x) (AY = 2,6-di-i-Pr-phenoxy; Ar' = 2,4-di-MeC6H2; x = 0, 5; x = 1, 6; x = 2, 7; x = 3, 8) featuring three six-membered chelating rings (5) to three five-membered chelating rings (8) in a stepwise fashion through 6 and 7 were synthesized from the corresponding trihydroxy chelating ligands 1-4, respectively, using an equimolar mixture of Ti(O-i-Pr)(4) and 2,6-di-i-Pr-phenol. The molecular structures of 5 and 6, determined by X-ray means, revealed that in both of these complexes the transannular N-Ti bond lengths [2.305(2) Angstrom, 5; 2.287(4) Angstrom, 6] are at the short end of the range for titanatranes possessing three five-membered rings. These compounds show good catalytic activity for the bulk homopolymerization of l- and rac-lactide at 130 degreesC.
