Abstract
Three polynuclear dioxomolybdenum(VI) complexes [MoO2(5MeO-SalTSC-4-Ph)]n, [MoO2(5MeO-SalTSC-4-Me)]n and [{MoO2(5-MeO-SalTSC)}·½CH3CN] n, two mononuclear [MoO2(5MeO-SalTSC-4-Me)(MeOH)] and [MoO2(5MeO-SalTSC)(MeOH)]·MeOH and hybrid organic-inorganic POM complex [MoO2(H5MeO-SalTSC-4Me)(CH3CN)]2Mo6O19 have been synthesized by the reaction of [MoO2(acac)2] and corresponding thiosemicarbazone ligand in 1:1 and 7:1 molar ratio, respectively. Mononuclear complexes were obtained from a methanolic solution, whereas polynuclear and POM hybrid complex from acetonitrile. Complexes were characterized by the IR spectroscopy, elemental and thermogravimetric analysis. Additionally, molecular and crystal structures of mononuclear complexes were determined by the single crystal X-ray diffraction. Catalytic activity of all complexes was tested in the solvent-free epoxidation of cis-cyclooctene, cyclohexene and (R)-limonene with TBHP as an oxidant and low catalyst loading (0.05 %).
Abstract (croatian)
Reakcijom [MoO2(acac)2] i odgovarajućeg tiosemikarbazonskog liganda u 1:1 odnosno 1:7 molarnom omjeru pripravljeni su kompleksni spojevi molibdena(VI): polinuklearni [MoO2(5MeO-SalTSC-4-Ph)]n, [MoO2(5MeO-SalTSC-4-Me)]n i [{MoO2(5-MeOSalTSC) }·½CH3CN]n, mononuklearni [MoO2(5MeO-SalTSC-4-Me)(MeOH)] i [MoO2(5MeO-SalTSC)(MeOH)]·MeOH te hibridni organsko-anorganski polioksomolibdatni spoj [MoO2(H5MeO-SalTSC-4Me)(CH3CN)]2Mo6O19. Mononuklearni kompleksi dobiveni su iz metanolne otopine, a polinuklearni i hibridni iz acetonitrila. Kompleksi su identificirani IR spektroskopijom, elementnom i termogravimetrijskom analizom te je dodatno, difrakcijom rentgenskog zračenja na monokristalnom uzorku, određena molekulska i kristalna struktura mononuklearnih kompleksa. Katalitička aktivnost pripravljenih spojeva ispitana je u reakcijama epoksidacije olefina (cis-ciklooktena, cikloheksena i (R)-limonena) s TBHP-om u uvjetima bez otapala. Za epoksidaciju je korišteno 0,05 % katalizatora u odnosu na supstrat.
