Asymmetric Reactions of N-Phosphonyl/Phosphoryl Imines

open access: yesMolecules, 2023
The asymmetric reactions of imines continued to attract the attention of the scientific community for decades. However, the stereoselective reactions of N-phosphonyl/phosphoryl imines remained less explored as compared to other N-substituted imines.

Effects of Through-Bond and Through-Space Conjugations on the Photoluminescence of Small Aromatic and Aliphatic Aldimines

open access: yesMolecules, 2022
Through-bond conjugation (TBC) and/or through-space conjugation (TSC) determine the photophysical properties of organic luminescent compounds. No systematic studies have been carried out to understand the transition from aromatic TBC to non-aromatic TSC ...

Influence of percentages of ethanol alcohol on the acidity and basal of various imines derived from N-formylpipridine [PDF]

open access: yesمجلة التربية والعلم, 2012
The project describes the influence of five different percentages of ethanol in a range between (10-50)% in a mixture of ethanol-water on the acidity of thirteen imines as derived from N-formyl-pipyridine. These five percentages of ethanol-water mixtures

Electronic interaction and oxygen vacancy engineering of g-C3N4/α-Bi2O3 Z-scheme heterojunction for enhanced photocatalytic aerobic oxidative homo-/hetero-coupling of amines to imines in aqueous phase

open access: yesGreen Carbon, 2023
Photocatalytic oxidation coupling of amines represents a green and cost-effective method for the synthesis of highly value-added imines under visible light irradiation. However, the catalytic efficiency was severely limited by poor visible light response

Mechanochemical Synthesis of Fluorinated Imines

open access: yesMolecules, 2022
A number of imines, including 12 new compounds, previously not reported in the literature, derived from variously fluorinated benzaldehydes and different anilines or chiral benzylamines were synthesized by a solvent-free mechanochemical method, which was
