摘要: Abstract The iron(II) complexes [Fe(N-N)3](OTf)2 (N-N = 2,2′- bipyridine, 1,10-phenanthroline and substituted derivatives) were employed as catalyst precursors for the oxidation of primary secondary alcohols, including glycerol. single-crystal structure [Fe(bipy)3](OTf)2 was determined by X-ray crystallography.The catalytic reactions performed using either H2O2 or tert-butilhydroperoxide (TBHP) oxidating agent, in mild experimental conditions: with all catalysts employed, alcohols oxidized to corresponding ketones up 100% yields, whereas other substrates gave lower conversions. Indications on nature catalytically active species, which is probably formed via dissociation a nitrogen ligand from iron center, obtained NMR ESI–MS spectra.
