Sažetak
Synthesis of the dioxomolybdenum(VI) complexes [MoO2(L3OMe)(EtOH)] (1), [MoO2(L4OMe)(EtOH)] (2)and [MoO2(LH)(EtOH)] (3) and dioxotungsten(VI) complexes [WO2(L3OMe)(EtOH)] (4), [WO2(L4OMe)EtOH)] (5) and [WO2(LH)]n (6a) was carried out using [MO2(C5H7O2)2] (M = Mo or W) and the corresponding aroylhydrazone ligand H2LR(3- methoxysalicylaldehyde 4-hydroxybenzhydrazone (H2L3OMe), 4-ethoxysalicylaldehyde 4- hydroxybenzhydrazone (H2L4OMe), or salicylaldehyde 4-hydroxybenzhydrazone (H2LH) in ethanol.Compounds obtained upon heating of the mononuclear complexes in acetonitrile or dichloromethane, [MO2(LR)n(1a– 6a) or [MoO2(L3OMe)]2(1b), respectively, were also investigated. Crystal and molecular structures of the mononuclear 1, 2and 3, polynuclear 1a×MeCN and dinuclear 1b complexes were determined by the single crystal X-ray diffraction method. Powder X- ray diffraction showed isostructurality of 1 and 4, and 2 and 5. The complexes were further characterized by elemental analysis, IR spectroscopy, TG and DSC analyses, and one- and two-dimensional NMR spectroscopy. The catalytic performances of 1–5 and 6a were investigated for epoxidation of cyclooctene using aqueous tert- butylhydroperoxide (TBHP)as the oxidant.
