  摘要：

  A systematic studies on complex formation between Mn(II) ions, 2,3,5,6-tetra(2-pyridyl)pyrazine and halide or pseudohalide (N-3(-), NCS- and N(CN)(2)(-)) ligands have been carried out and the following complexes [Mn-2(mu-Cl)(2)Cl-2(tppz)(2)] (1), [Mn2Cl2(mu-N-3-kappa N1)(2)(tppz)(2)] (2), [MnCl(SCN)(tppz)(H2O)]center dot H2O (3), [MnCl(dca)(tppz)(H2O)(0.57)(MeOH)(0.47)] (4), [Mn(NO3)(2)(tppz)(H2O)] (5), [Mn(N-3)(NO3)(tppz)(H2O)] (6), [Mn(SCN)(2)(tppz)] (7) and [Mn(NO3)(dca)(tppz)](n), (8) have been obtained. The compounds were characterized by elemental analysis, IR, EPR, magnetic measurements and X-ray analysis. Two of them (5 and 6) have been tested as catalysts in oxidation of alcohol to aldehydes/ketones using oxone (2KHSO(5)center dot KHSO4 center dot K2SO4) as an oxidant under biphasic reaction conditions (CH2Cl2/H2O) and tetra-n-butylammonium bromide as phase transfer agent under air at room temperature and as catalysts in oxidation of sulfides to sulfoxides with UHP (urea hydrogen peroxide) as oxidant.
