We report a theoretical study of the first silver-dependent enantiodivergent gold-catalysed reaction. The combination single chiral binuclear gold(I) chloride complex and silver perchlorate catalyses asymmetric intramolecular hydroamination alkenes affords both enantiomers products by applying simple solvent change from toluene to methanol. A gold-silver adduct that occurs only in methanol appe...

Choline chloride + levulinic acid deep eutectic solvent is studied as a suitable material for CO2 capturing purposes. The most relevant physicochemical properties of this solvent are reported together with the CO2 solubility as a function of temperature. The corrosivity of this solvent is studied showing better performance than amine-based solvents. A theoretical study using both density functi...

A reagent-controlled, diastereo- and enantioselective synthesis of anti- and syn-β-hydroxy-α-phenyl carboxylates has been achieved by the proper choice of solvent, temperature, alkoxy group, and amine for the diisopinocampheylboron-mediated asymmetric enolization-aldolization of phenylacetates. The pure diastereomers can be readily separated by column chromatography.

An effective and eco friendly procedure under microwave irradiation, for synthesis of symmetrical disubstituted alkyl and aryl ureas from amine hydrochlorides using water as solvent medium has been developed. Based on molecular docking studies on HIV-1 gp120, synthesized compounds were evaluated for HIV-1 gp120 – CD4 binding inhibition and these molecules showed micro molar range (0.047 μM to 4...

Alkyl bromides and chlorides can be reduced to the corresponding hydrocarbons utilizing zinc in the presence of an amine additive. The process takes place in water at ambient temperatures, enabled by a commercially available designer surfactant. The reaction medium can be readily recycled, and the amount of organic solvent invested for product isolation is minimal, leading to very low E Factors.

Mesoporous silica grafted with a tertiary amine was used as a basic nanocatalyst to promote in confined medium the enantioselective cascade rearrangement of enediynes based on the phenomenon of memory of chirality; the multi-substrates recyclable catalytic reagent could easily be recovered by simple filtration, and reused without any decrease in activity even when changing the solvent.

The title compound, (C3H10N2)2[AlF6]F·3H2O, was obtained using the solvothermal method with aluminium hydroxide, HF and propane-1,3-di-amine as precursors in ethanol as solvent. The structure consists of isolated [AlF6](3-) octa-hedra, diprotonated propane-1,3-di-amine cations [(H2dap)(2+)], free fluoride ions and water mol-ecules of solvation. The Al-F bond lengths in the octa-hedral [AlF6](3-...

In the title complex, [InCl(2)(C(24)H(21)N(7))]Cl·C(2)H(5)OH·2H(2)O, the In(III) ion is coordinated by four N atoms from the tris-(benz-imidazol-2-ylmeth-yl)amine (NTB) ligand and two Cl atoms in a distorted octa-hedral environment. In the crystal structure, inter-molecular N-H⋯O, O-H⋯O, O-H⋯Cl and weak C-H⋯Cl hydrogen bonds connect the cations, anions and solvent mol-ecules into a three-dimens...

a mild and efficient one-pot three-component and environmentally benign approach for the synthesis of a wide range of hydantoin annulated derivatives has been described. a multi-component reaction between a carbonyl compounds (ketone or aldehyde), potassium cyanide and ammonium carbonate (as cyanating agent and amine source, respectively leads to the formation of hydantoins. the proposed optimi...

Greenhouse gases emission is known as the main factor of climate change, and carbon dioxide (CO2) makes up vast majority of them. Carbon capture and storage (CCS) is a vital technology to mitigate industrial CO2 emissions, which is mainly generated in power plants. Currently, post-combustion capture based on aqueous amine scrubbing is considered as the most suitable technology for CO2 capture. ...
