  摘要：

  A new class of air stable and structurally well-defined cobalt complexes with unsymmetrical pincer type ligands ([2-(ArN=CMe)-6-(PY)C5H3N]CoCl2) (Ar = -C6H5, PY = pyrazol-1-yl, 5a; Ar = 2,4,6-Me3C6H2 Py=pyrazol-1-yl, 5b; Ar = 2,6-(Pr2C6H3)-Pr-1.

Upon activation by methylaluminoxane (MAO) in toluene at room temperature, all complexes initiate polymerization of 1,3-butadiene (polymer yields: 65-99%), affording polybutadiene with excellent cis-1,4 regularity (97.5-98.7%). The polymer yields and properties in terms of molecular weight and distribution are well controlled by the substituents on iminoaryl rings and pyrazole rings. Selectivity switch from cis-1,4 to syndio-1,2 was also achievable by adding phosphine as microstructure regulator. (C) 2013 Elsevier B.V. All rights reserved.

  ine ligands and their ruthenium(II) and nickel(II) NNN complexes were synthesized. The Ru(II) complex catalysts have been fully characterized and exhibited good to excellent catalytic activity in the transfer hydrogenation (TH) of ketones in refluxing 2-propanol. These results have demonstrated rare examples of active ruthenium(II) NNN complex catalysts that do not feature a N–H functionality for TH

  合成了新型的半不对称的不对称的2-（1-芳基）-6-（吡唑-1-基）吡啶配体及其钌（II）和镍（II）NNN配合物。Ru（II）络合物催化剂已得到充分表征，并在回流的2-丙醇中的酮转移加氢（TH）中表现出良好的催化活性。这些结果证明了稀有的活性钌（II）NNN络合物催化剂的实例，这些催化剂不具有酮TH的N–H官能度。
