Three-Component Reaction of Benzylamines, Diethyl Phosphite and Triethyl Orthoformate: Dependence of the Reaction Course on the Structural Features of the Substrates and Reaction Conditions

Molecules, 2017
The reaction between benzyl amines, triethyl orthoformate, and diethyl phosphite affords either bisphosphonic (compound 1) or N-benzylaminobenzylphosphonic (compound 2) acid depending on the reaction conditions.

Rigid and concave, 2,4-cis-substituted azetidine derivatives: A platform for asymmetric catalysis. [PDF]

, 2018
A series of single enantiomer, 2,4-cis-disubstituted amino azetidines were synthesised and used as ligands for copper-catalysed Henry reactions of aldehydes with nitromethane. Optimisation of ligand substituents and the reaction conditions was conducted.

Surface Sulfate Modification Promoted Excitons Extraction of BiOBr Nanosheets for Efficient 1O2 Photosynthesis and Chlorophenols Dechlorination

Rare Metals, EarlyView.
ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−

Switchable Reactivities of Metalated Phosphasilenes Regulated by Reversible 1,2‐Metal Migration

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
We develop novel strategies for the facile synthesis of anionic phosphasilenes in the forms of both P‐metalation and Si‐metalation. The P‐metalated phosphasilene displays a pronounced π‐bond‐driven reactivity toward robust inert molecules, whereas the Si‐metalated analogue behaves as a silylene equivalent via a retro‐1,2‐silver migration.

White‐Light Flexible Crystal With 180° Folding Induced by Halogen‐Bond Network in Organic‐Inorganic Hybrid Perovskite

Rare Metals, EarlyView.
ABSTRACT Organic‐inorganic hybrid perovskites (OIHPs) with white‐light emission have significant potential in solid‐state lighting and display due to the designable structure and excellent luminescent properties. However, OIHPs are prone to damage during bending due to the brittleness of crystals, which limits their application in the field of flexible

Hippocampal subfield differences in people with and without recreational ketamine use: Insights from multi‐modal neuroimaging

Addiction, EarlyView.
Abstract Background and aims Recreational ketamine use has increased globally and is associated with psychiatric and cognitive concerns. The hippocampus in preclinical models shows damage and working‐memory disruption with repeated dosing. However, whether specific hippocampal subregions may differ in people with chronic ketamine use remains unclear ...
