A new manganese complex of the formula [Mn(tptz)(OH2)3](CF3SO3)2·EtOH, (1, where tptz = (2,4,6-tris(2-pyridyl)-1,3,5-triazine) is presented, exhibiting an excellent catalytic activity and selectivity in oxidation of various sulfides to the corresponding sulfoxides with UHP (urea hydrogen peroxide) as oxidant under air at room temperature. A modified preparation procedure produces another new manganese complex of the formula [Mn(tptz)(CH3COO)(OH2)2](CF3SO3)·3H2O (2). X-ray structures of both Mn(II) complexes, properties (elemental analysis, electrochemistry, EPR, IR, Raman, and UV–Vis spectra), as well as DFT studies results are reported.
The synthesis, structures, properties (including catalytic activity) and DFT studies of two new mononuclear manganese complexes with tptz (2,4,6-tris(2-pyridyl)-1,3,5-triazine) ligand are reported.Figure optionsDownload as PowerPoint slide
