Titanium-silica catalysts, obtained by grafting titanocene dichloride onto mesoporous silica (MCM-41 and MCM-48) nanosized pyrogenic silica, were tested in the epoxidation of methyl oleate using aqueous hydrogen peroxide. All titanium-containing materials, combined with slow addition peroxide, showed good catalytic activity comparable behaviour terms conversion, selectivity yield epoxystearate, notwithstanding morphology texture support. By optimizing reaction conditions (especially,...
Abstract Electrochemical amidation of the C( sp 2 )−H and 3 bonds broad spectrum arenes toward direct synthesis anilides N ‐benzylamides under mild conditions (room temperature, ambient pressure) in absence metal catalyst external oxidizing agents using nitriles RCN (R=Me, Et) as amide source is described. This electrochemical approach features moderate to high yields, a scope with different functional groups amenable gram scale synthesis. The key role hydroxyl radical inductor generated...
Throw out the anchor! A new approach for preparation of heterogeneous catalysts based on a covalent anchoring an innovative multifunctional titanosisesquioxane inner surface silanols mesoporous silicas (SBA-15 and non-ordered silica) is proposed (see figure).
The development of convenient methods for the synthesis heterocyclic compounds that are highly important search pharmacological substances and in other spheres human activity is among most relevant fields organic chemistry. Two functional groups arenes located adjacent positions benzene ring can provide a fused ring. If at least one two <i>ortho</i>-functional contains nitrogen atom, heterocycle formed upon cyclization. nitro group often chosen as nitrogen-containing...
Ionic liquids based on imidazoles find various applications in organic synthesis, catalysis, and biochemical processes. In this paper, the possibility of using IL for synthesis phosphorylacetic acid hydrazides, which are obtained by Arbuzov reaction, classical version is interaction trialkyl phosphites with alkyl halides, considered. The ability ionic to increase nucleophilicity trivalent phosphorus esters makes it possible activate reaction halides. Phosphorylacetic hydrazide - Phosenazide,...
The article discusses one of the possible ways developing laboratory practical work in organic chemistry at technological university order to bring it line with modern requirements. It is revealed that educational its current state does not sufficiently prepare students, including for research related establishing relationships between properties substances and their chemical structure. In solve this problem, using small amounts were developed tested process. first nitrosation phenols...
Macrocyclic compounds - calixresorcins are a cavity system with rigid cup-shaped containing four resorcinol rings, which provide π-electron-rich and polar hydroxyl groups at the upper rim of resorcinol[4]arene. In this paper, we present data on production «guest-host» complexes C alkylated in armchair conformation Phosenazide ([2-(diphenylphosphoryl)acetohydrazide]), exists form two crystalline modifications I II. NMR, UV IR spectroscopy methods were used to assess nature interaction between...
Abstract Limonene oxide is an intermediate getting growing attention in industrial chemistry. A series of Ti‐MCM‐41 heterogeneous catalysts with different hydrophilic/hydrophobic character, prepared by post‐synthesis silylation hexamethyldisilazane (HMDS), were studied the liquid‐phase epoxidation limonene tert ‐butylhydroperoxide (TBHP). maximum yield 84 % was obtained over a partially silylated catalyst surface coverage 55 %.
This review systematically summarizes recent literature data on the chemistry of epoxides published from 2010 to 2021 and, in part, 2022. Epoxides are an important class compounds, which valuable building blocks design new structures serving as basis for many practically compounds. Epoxy derivatives have long attracted attention synthetic chemists, confirmed by a number name reactions associated with their synthesis. The describes methods synthesis epoxy including both improved classical and...
Bidentate ligands of the type Mes*PC(R)Py ((E)-2, R = H; (Z)-9, SiMe3; Mes* supermesityl 2,4,6-tri-tert-butylphenyl; Py 2-pyridyl) were synthesized. Ligand (E)-2 was synthesized by reacting Mes*P(Li)SiMe2(t-Bu) (4) with 2-pyridinecarboxaldehyde. (Z)-9 via a PdCl2(dppb)-catalyzed coupling reaction between 2-bromopyridine and Mes*PC(SiMe3)M ((E)-7, M ZnCl; (Z)-8, MgBr). Compound also characterized an X-ray crystal structure determination; it has planar (E)-configuration. The complexes...
Abstract Poorly water‐soluble calix[4]resorcinarenes modified with amino acid (Ala, Val) at the upper rim formed a mixed system micelles of monocationic surfactants cetyltrimethylammonium bromide, cetyldimethyl(2‐hydroxyethyl)ammonium and dicationic (gemini) surfactants, alkanediyl‐α,ω‐ bis (dimethyltetradecylammonium bromides (14‐s‐14, where s = 2, 4, or 6). UV–Vis DLS methods demonstrated that micellar systems surfactant/functionalized calix[4]resorcinarene underwent structural changes...
A complex of physicochemical methods showed that the water-insoluble glycine-based сalix [4]resorcinol is solubilized by sodium dodecyl sulfate (SDS) micelles, thus not affecting character surfactant aggregation.pH-dependent solubilization hydrophobic drug 2,2'-bibenzimidazole (BBI) in SDS micellar solutions presence this macrocycle was shown.At acidic conditions micelles leads to a decrease joint BBI aqueous solutions.In case, protonation nitrogen atom at upper rim calixarene favors its due...
Two approaches to the synthesis of calix[4]resorcines bearing phosphonates and phosphonium fragments at lower rim were elaborated. One based on methodology for octols by fourfold condensation 4-substituted benzaldehydes with resorcinol its derivatives. The calixaren matrix was used as a starting material functionalization in another method. Both reaction phosphorylation arylhalides derivatives P(III) acids presence Ni(II) compounds. Phosphorylated calyx[4]resorcines further modified upper...
An electrochemical reaction between quinoline N-oxides and morpholine was developed by using Cu(OAc)2 as a catalyst, generating products of 4-aminoquinoline in CH2Cl2 or 2-aminoquinoline CH3CN good yields. With an increase the amount electricity passed, product deoxygenates with formation aminoquinolines. The advantages are mild conditions, room temperature, use rather than its derivatives, ability to control process when electrolysis conditions change. Bisubstituted has also been obtained....
Two polymorphic forms of a conformationally flexible molecule, 5-[(Diphenylphosphoryl)methyl]-4-(prop-2-en-1-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione, were obtained by crystallization and characterized X-ray diffraction analysis differential scanning calorimetry. The relative stability was estimated with DFT calculations crystal structures isolated molecules. It turns out, that in the first more dense polymorph higher cohesion energy lattice energy, molecule adopts an energetically...
