We have observed that the superoxide anion reacts with VO(salen), but not with VO(saldpt), where H2(salen) and H2(saldpt) are Schiff base ligands derived from salicylaldehyde and ethylenediamine or dipropylenetriamine, respectively. Based on the electrochemical, ESR, and UV spectroscopic studies of the reaction mixture, it was concluded that the superox­ ide anion reacts with VO(salen) to oxidi...

The catalytic properties of bulky water-soluble salen complexes in the oxidation of isoeugenol (2-methoxy-4-(1-propenyl) phenol) have been investigated in aqueous ethanol solutions in order to obtain a mixture of polymeric compounds through dehydrogenative polymerization. The average molecular weight of dehydrogenated polymers (DHPs) was monitored by GPC and correlated to reaction conditions su...

Alkane functionalization using safe and low-energy processes is of great interest to industry academia. Aiming contribute the process saturated hydrocarbon functionalization, we have studied a set three manganese(III) complexes as catalysts for promoting oxidation hydrocarbons (cyclohexane methylcyclohexane) in presence hydrogen peroxide or trichloroisocyanuric acid (TCCA). The mononuclear comp...

Treatment of [N(n)Bu(4)][Os(VI)(N)Cl(4)] with a stoichiometric amount of H(2)L (L = N,N'-bis(salicylidene)-o-cyclohexylenediamine dianion) in the presence of PF(6)(-) or ClO(4)(-) in MeOH affords [Os(VI)(N)(L)(OH(2))](PF(6)) 1a and [Os(VI)(N)(L)(CH(3)OH)](ClO(4)) 1b, respectively. The structure of 1b has been determined by X-ray crystallography and the Os≡N bond distance is 1.627(3) Å. In the p...

Extraction-separation of Eu(III) and Th(IV) ions from nitrate media into the ionic liquid 1-hexyl-3-methylimidazolium hexafluorophosphate by a phosphorylated salen extractant, bis(chlorophosphoryle)decahydro-2,4-di(2-hydroxyphenyl)benzo[d][1,3,6]oxadiazepine (DPO), is investigated. It is found that Eu(III) ions are extracted via a solvation mechanism, and the extraction of Th(IV) i...

The electrocatalytic reduction of carbon dioxide (CO2) into added-value products is a promising alternative to completing the cycle atmospheric CO2. We report two new platinum complexes—a salen-like naphthalene (PtL1) and hydroxy-substituted salpn (PtL2)—that are capable activating CO2 produce monoxide (CO). predominant keto tautomer non-innocent ligands was determined using DFT calculations UV...
