Nowadays, the effective processing of natural monoterpenes that constitute renewable biomass found in post-production waste into products are starting materials for synthesis valuable compounds is a way to ensure independence from non-renewable fossil fuels and can contribute reducing global carbon dioxide emissions. The presented research aims determine, based on DFT calculations, activity reactivity limonene, an organic substrate used previous preparative analyses, comparison selected such...
The flavonoid-based macroinitiator was received for the first time by transesterification reaction of quercetin with 2-bromoisobutyryl bromide. In accordance “grafting from” strategy, a naturally-occurring star-like polymer polar 3,3',4',5,6-pentahydroxyflavone core and hydrophobic poly( tert -butyl acrylate) (P t BA) side arms synthesized via simplified electrochemically mediated ATRP ( se ATRP), utilizing only 78 ppm weight (wt) catalytic Cu II complex. To demonstrate possibility temporal...
The use of dioxygen as an oxidant in fine chemicals production is emerging problem chemistry for environmental and economical reasons. In acetonitrile, the [(N4Py)FeII]2+ complex, [N4Py-N,N-bis(2-pyridylmethyl)-N-(bis-2-pyridylmethyl)amine] presence substrate activates oxygenation cyclohexene limonene. Cyclohexane oxidized mainly to 2-cyclohexen-1-one, 2-cyclohexen-1-ol, oxide formed much smaller amounts. Limonene gives main products limonene oxide, carvone, carveol. Perillaldehyde perillyl...
Iron complexes are particularly interesting as catalyst systems over the other transition metals (including noble metals) due to iron’s high natural abundance and mediation in important biological processes, therefore making them non-toxic, cost-effective, biocompatible. Both homogeneous heterogeneous catalysis mediated by iron a metal have found applications many industries, including oxidation, C-C bond formation, hydrocarboxylation dehydration, hydrogenation reduction reactions of low...
Abstract It has been found that hydrogen peroxide can act as an oxidant and a reductant of transition metal complexes in acetonitrile. Therefore, the examples catalytic currents oxidants reductants described. In case Co(acac) 3 both types are present single cyclic‐voltammetric scan.
Spontaneity criteria for processes with useful (especially electrical) work have been discussed based on total differentials of thermodynamic functions. Reaction Gibbs energy (ΔrG) and electrochemical reaction (ΔrG̃) juxtaposed. Three-dimensional graphs showing the dependencies ΔrG̃ extent (ξ) cell voltage (φR – φL), in connection their sections, enable both coherent intuitive discussion equilibrium systems. It was clearly indicated that important, commonly known can be justified illustrated...
Manganese(II) complex [(Bn-tpen)MnII]2+ activated dioxygen for oxidation of cyclohexene in acetonitrile (MeCN) and methanol (MeOH). In MeCN, ketone (2-cyclohexen-1-one), alcohol (2-cyclohexen-1-ol) small amounts epoxide (cyclohexene oxide) were produced this reaction, while MeOH only was formed. the most efficient experiment, combination 2.5 × 10-4 mol% 4 M under atmosphere (pO2 = 1 atm) MeCN after 24 h gave TON equal to 716, main products (196 mM) (147 mM), whereas formed insignificant (15...
Abstract The iron and manganese complexes that activate oxygen atom play multiple role in technologically relevant reactions as well biological transformations, which exist different redox states. Among them, high-valent oxo intermediate seems to be the most important one. Iron, and/or manganese-based processes have found application many areas, starting from catalysis sustainable technologies, through DNA oxidative cleavage, new substances useful chemotherapeutic drugs. This review is not...
[(Bn-tpen)Fe
[(salen)FeIII]+MeCN complex is a useful catalyst for cyclohexene oxidation with dioxygen. As the main products, ketone and alcohol are formed. In acetonitrile, [(salen)FeII]MeCN rapidly oxidized by dioxygen, forming iron(III) species. Voltammetric electroreduction of in presence dioxygen causes increase current observed, which indicates existence catalytic effect. Further transformations oxygen-activated salen generate an effective catalyst. Based on electrochemical results, as well DFT...
Abstract The products of hydroxyalkylation N,N’-bis(2-hydroxypropyl)urea (BHPU) with large molar excess propylene carbonate (PC) posses enhanced thermal stability. These and 4,4’-diphenylmethane diisocyanate were used as substrates for obtaining rigid polyurethane foams, which had high stability low water uptake.
