A large number of enantiopure substances, such as those with tetrasubstituted carbon centres bearing several similar substituents, are inaccessible due to the incapability of chiral catalysts/ligands to recognize those substrates. Here, the authors develop kinetic resolution of auxiliary adjacent alcohols (KRA*) strategy to access various optically...

The direct deoxygenative coupling of aldehydes or ketones to construct C(sp3)−C(sp3) bond remains a scientific challenge. Here the authors use a nickel−catalyzed reductive homo-coupling of moisture- and air-stable hydrazones generated in-situ from naturally abundant aldehydes and ketones to construct challenging C(sp3)−C(sp3) bonds.

Luteolin is a flavonoid found in a wide range of plant materials, including commonly eaten fruits and vegetables. It displays a wide range of biological activities but is known to have poor bioavailability. In this study, ten different mono-acyl (nine 5-O-acyl and one 7-O-acyl) derivatives of luteolin were synthesised for the purpose of improving b...

In hybrid perovskites, the driving forces of an order–disorder transition that arise from the organic cation and inorganic framework cannot be easily untangled. Here, the authors introduce a cage-in-framework structure in which reorientation of the cage cation does not alter the cubic symmetry of the perovskite lattice.

This study introduces a practical approach to fabricate a novel hybrid acidic catalyst, namely sulfamic acid pyromellitic diamide-functionalized MCM-41 (MCM-41-APS-PMDA-NHSO3H). Various techniques such as FTIR, TGA, XRD, BET, FESEM, and EDX were used to confirm its structural characteristics. The efficiency of the new MCM-41-APS-PMDA-NHSO3H organos...

Although enols and enolates addition to unactivated alkynes is used for carbon-carbon bond modification a catalytic asymmetric alkyne with 1,3-dicarbonyl compound has been elusive. Here, the authors achieve this using the synergistic activation of chiral N,N′-dioxide-indium(III) or nickel(II) Lewis acid and achiral gold(I) π-acid.”

We compared the effects of preservation and storage methods on total alkalinity (AT) of seawater, estuarine water, freshwater, and groundwater samples stored for 0–6 months. Water samples, untreated or treated with HgCl2, 0.45 µm filtration, or filtration plus HgCl2, were stored in polypropylene or borosilicate glass vials for 0, 1, or 6 months. Me...
