  Observation of Internal Electron Transfer in Bulky Allyl Ytterbium Complexes with Substituted Terpyridine Ligands

  摘要：

  A series of new bulky allyl terpyridyl-ytterbium complexes have been synthesized to determine the effect of allyl ligands on the internal charge-transfer process that exists in these materials. Compared to the pentamethylcyclopentadienyl-ytterbocene compound Cp*Yb-2(tpyCN) (nu(C N) = 2172 cm(-1)), the symmetrically substituted allyl complex [1,3-(SiMe3)(2)C3H3](2)Yb(tpyCN) possesses a markedly lowered C N frequency of 2130 cm(-1). Furthermore, the electronic nature of these bulky allyl complexes can be tuned, as demonstrated by the C N frequency of the asymmetric derivatives [1-(SiMe3)C3H4]2Yb(tpyCN) and [1-(SiPh3)-3-(SiMe3)C3H3](2)Yb(tpyCN) (2171 and 2164 cm(-1), respectively). The differences in these frequencies can be attributed to differences in the ligands' steric and electronic character. Single-crystal X-ray characterization of [1,3-(SiMe3)(2)C3H3](2)Yb(tpy) reveals that the allyl moiety possesses shorter Yb-C and Yb-N bond distances than the Cp* analogue. The magnetic susceptibility data for [1,3-(SiMe3)(2)C3H3](2)Yb(tpy) departs dramatically from the Curie law, with a room-temperature magnetic moment of 2.95 mu(B).

  碱金属阳离子在中性和阴离子烯丙基镧系元素络合物引发的MMA聚合中的作用

  摘要：

  2或3当量的1,3-双（三甲基硅烷基）烯丙基钾（K [1,3-（SiMe 3）2 C 3 H 3 ] = K [A']）与Ce，Nd的三氟甲磺酸盐反应Eu，Tb和Yb给出相应的中性双-（Yb，Eu）和三-（Ce，Nd，Tb）烯丙基镧系元素络合物，产率为40％至80％。这些配合物，其已经被晶体学表征，发起甲基丙烯酸甲酯（MMA）的聚合，但具有差的转换频率时与该类型K [LNA”的相应的盐配合物相比，3 ]。K [A']本身会引发MMA聚合，但是它在盐配合物中作为离子对存在可能有助于杂金属镧系元素催化剂的活性。
