Abstract:

The kinetics and mechanism of the reaction of ozone with acetoxytoluenes in an acetic anhydride solution in the presence of manganese acetate have been studied. The main reaction products under these conditions are hydroxybenzyl alcohols in the form of the corresponding acetoxybenzyl acetates (65-77%). The effect of manganese (II) acetate on the selectivity of oxidation with respect to the methyl group has been studied. The mechanism of redox catalysis is considered, which explains the obtained experimental data.

Abstract:

The reaction of the open-chain tetrapyrrolic ligand 2,2'-bidipyrrin with molecular dioxygen in the presence of a catalytic amount of manganese(II)-acetate was found to produce 10,10'-diformyl-2,2'-bidipyrrin with a remarkable selectivity. To identify the active oxidant in this transformation, 2,2'-bidipyrrin was treated with potassium superoxide, sodium peroxide and manganese(III) acetate, respectively, in dry DMF. While superoxide produces the dialdehyde in high yield, the treatment with peroxide or manganese(III) acetate leads to decomposition only. Nickel(II)-, palladium(II)- and copper(II)

The nanoparticles were produced from a solution of zinc acetate dihydrate and manganese(II) acetate tetrahydrate using ethylene glycol as solvent. The content of Mn2+ in Zn1− x Mn x O ranged from 1 to 25 mol %. The following properties of the nanostructures were investigated: skeleton density, specific surface area (SSA), phase purity (XRD), lattice parameters, dopant content, average particle size, crystallite size distribution, morphology. The average particle size of Zn1− x Mn x O

Abstract:

5-Hydroxyisophthalic acid is of practical interest in the synthesis of polymers, drugs, cosmetics. The methods for its preparation described in the literature are characterized by a number of significant drawbacks, which hinders the use of this compound in the development of new materials with valuable consumer properties. In this regard, a method for the synthesis of 5-hydroxyisophthalic acid by the oxidation of 3, 5-xylenol has been developed. It has been established that the hydroxyl group inhibits the oxidation of methyl groups; therefore, to carry out oxidative transformations, the hydrox

Abstract:

In this study, the selective oxidation of methylbenzenes by ozone in the liquid phase was investigated. It was established that the ozonation of methylbenzenes in acetic acid in the presence of Mn(II) acetate and NaBr is ineffective, as the reaction predominantly leads to the destruction of the aromatic system. The use of the "CH3COOH–H2SO4" system is shown to direct the process towards the oxidation of the methyl group, significantly increasing the rate and selectivity of the process. A notable feature of manganese(II) bromide catalysis is the absence of substantial amounts of aromatic alcoho

Li [ Li 0.2 Mn 0.56 Ni 0.16 Co 0.08] O 2 cathode materials for Li -ion batteries were synthesized by a facile sol–gel method followed by calcination at various temperatures (700°C, 800°C and 900°C). Lithium acetate dihydrate, manganese (II) acetate tetrahydrate, nickel (II) acetate tetrahydrate and cobalt (II) acetate tetrahydrate are employed as the metal precursors, and citric acid monohydrate as the chelating agent. For the obtained Li [ Li 0.2 Mn 0.56 Ni 0.16 Co 0.08] O 2 materials, the metal components existed in the form of Mn 4+, Ni 2+ and Co 3+, and their molar ratio was in good agreem

An acyclic hexadentate diimine ligand, H4L1, was prepared in situ in methanol by the condensation of 1,4-diformyl-2,3-dihydroxybenzene (1) with 2-aminoethanol, and complexed directly with two equivalents of MnII(OAc)2·4H2O or MnIII(OAc)3·2H2O, or with one equivalent of each. All three of these one-pot reactions gave the mixed-valent tetrametallic complex [MnII2MnIII2(L1)2(OAc)2(solvents)4], [2(solvents)4]. An X-ray crystal structure determination on [2(MeOH)4]·2MeOH revealed a centre of inversion in the middle of the complex. The four metal ions are in an almost planar array, sandwiched by two

Plasmodium falciparum is a fast-evolving parasite responsible for the fatal disease malaria, making it crucial to renew our therapeutic arsenal. Modulating the artemisinin’s endoperoxide pharmacophore is a promising route to synthesizing new antimalarial derivatives. For the first step of our 20 mmol scale synthesis, catalyzed by manganese (III) acetylacetonate, we applied the conditions previously described in the literature to one of our low-yielding asymmetrically disubstituted alkenes, (2-methylallyl)benzene. Under conditions designed for alkyl derivatives, manganese (II) and (III) acetate

Abstract:

A series of layered compounds of the formula {[Mn2(radical)3](ClO4)}n was obtained by a reaction (in methanol) of manganese(II) acetate with 2-(2-benzimidazolyl)-4,4,5,5-tetramethylimidazolidinyl-1-oxy-3-oxides fluorinated on the benzene ring and by successive addition of sodium perchlorate. This study showed that the magnetic properties of the complexes are sensitive to the number and arrangement of fluorine atoms in the paramagnetic ligands. It was found that the heterospin complex with 4-FBzIm-NN behaves as a magnet with Curie temperature TC = 50 K, which is close to that of the {[Mn2(BzIm-
