A toluene-soluble molybdenum(vi) complex containing a bulky hydrophobic substituent, (Et4N)2[Mo(VI)O2{1,2-S2-3,6-(RCONH)2C6H2}2] (R = (4-(t)BuC6H4)3C), was dissolved in the hydrophobic core of a micelle in an aqueous medium and catalyzed the biomimetic reduction of an amine N-oxide by an NADH analog. The kinetic isotope effect of solvent water clearly indicates that water molecules are essentia...

One-pot reaction of aldehydes or ketons with aniline derivatives was performed using NaBH4 and Fe3O4 magnetic nanoparticles (MNPs). The optimum amount of Fe3O4 MNPs was 5 mol% under solvent free condition. The corresponding products were obtained in good to excellent yields. The magnetically recoverable iron oxide nanoparticles are found to be efficient for synthesis of amine derivatives. These...

A one pot green three‐component coupling reaction of aldehyde, phenylacetylene, and amine derivatives in the presence of copper (II)–thioamide combination as a novel and efficient heterogeneous catalyst under solvent–free conditions is reported. The catalyst displayed high activity and afforded the corresponding propargylamines in good to high yields. The key to this procedure was the generatio...

In the toluene hemisolvated tripodal tris-(2-amino-ethyl)amine Schiff base, C(30)H(33)Cl(3)N(4)O(3)·0.5C(7)H(8), one of the three imino N atoms is protonated, forming a hydrogen bond with the O atom at an adjacent benzene ring. The other two imino N atoms act as hydrogen-bond acceptors from phenolate OH groups. The toluene solvent mol-ecule is disordered about a centre of inversion.

Full recovery of interfacial bond strength after complete fiber/matrix debonding is achieved with a microencapsulated solvent-based healing chemistry. The surface of a glass fiber is functionalized with microcapsules containing varying concentrations of reactive epoxy resin and ethyl phenylacetate (EPA) solvent. Microbond specimens consisting of a single fiber and a microdroplet of epoxy are te...

The studies performed about electrochemical oxidation 2-amino-4-methylphenol indicate that ortho-quinone yielded through oxidation of this chemical compound was unstable and it could be used as Michael acceptor under solvent influences, carrier electrolyte, additives and could be transformed into the various compounds in the form of 1-4 addition Michael reaction. Based on this, in the paper fir...

Two independent mol-ecules of the title solvated complex, [V(C16H14N2O2)O]·CH3OH, also known as [N,N'-bis-(salicyl-idene)ethyl-enedi-amine]-oxidovanadium(IV) or vanadyl salen, crystallize in the asymmetric unit. Each disordered methanol solvent mol-ecule [occupancy ratios 0.678 (4):0.322 (4) and 0.750 (5):0.250 (5)] is linked to a [N,N'-bis-(salicyl-idene)ethyl-enedi-amine]-oxidovanadium(IV) mo...

5-(3-Chlorophenyl)-1,3,4-thiadiazol-2-amine 2 was synthesized and employed to synthesize new 1,3,4-thiadiazole 1,3,4-thiadiazolo[3,2-a]pyrimidine derivatives via reactions with variant electrophilic reagents under solvent-free conditions. The chemical structures of these novel compounds were elucidated scrupulously by aiding elemental data spectroscopic techniques. evaluated for the insecticida...

Climate change occurs as a result of absorption of infrared radiation which heats the atmosphere. Greenhouse gas emissions can increase the earth’s average temperatures since the majority of greenhouse gases are carbon dioxide (CO2). Fossil fuels have historically played a major role as the world’s primary source of energy and will continue to assume that role for at least the next few decades....

Graph Machine Based-QSAR Approach for Modeling Thermodynamic Properties of Amines: Application to CO2 Capture in Postcombustion — Amine scrubbing is usually considered as the most efficient technology for CO2 mitigation through postcombustion Carbon Capture and Storage (CCS). However, optimization of the amine structure to improve the solvent properties requires to sample a large number of poss...
