Preparation of a Reactive Phosphorus/nitrogen-Based Intumescent Flame Retardant Coating for Cotton Fabrics

Journal of Natural Fibers, 2023
This study focuses on the synthesis of a reactive phosphorus-/nitrogen-based intumescent flame retardant (IFR) agent using diethyl phosphite, urea, and glutaraldehyde through Kabachnik-Fields reaction. We further studied the potential applications in IFR

Microwave-assisted synthesis of N,N-bis(phosphinoylmethyl)amines and N,N,N-tris(phosphinoylmethyl)amines bearing different substituents on the phosphorus atoms

Beilstein Journal of Organic Chemistry, 2019
A family of N,N-bis(phosphinoylmethyl)amines bearing different substituents on the phosphorus atoms was synthesized by the microwave-assisted and catalyst-free Kabachnik–Fields reaction of (aminomethyl)phosphine oxides with paraformaldehyde and ...

Generation of rectangular optical waves by relativistic clipping

, 2013
Theoretical results are reported, concerning the reflection and transmission of few-cycle laser pulses on a very thin conducting layer, which may represent the surface current density of the massless charges of graphene.

Switching the N‐Alkylation of Arylamines with Benzyl Alcohols to Imine Formation Enables the One‐Pot Synthesis of Enantioenriched α‐N‐Alkylaminophosphonates

European Journal of Organic Chemistry, Volume 2019, Issue 20, Page 3105-3111, June 2, 2019., 2019
The base‐free N‐alkylation of anilines with benzylic alcohols can be switched in favor of imine formation simply by switching between a closed and an open reaction system. Further functionalization of the in situ synthesized imine leads to α‐N‐alkylaminophosphonates via a one‐pot procedure in an atom‐economic fashion.

A Review of Solvate Ionic Liquids: Physical Parameters and Synthetic Applications

Frontiers in Chemistry, 2019
Solvate Ionic Liquids (SILs) are a relatively new class of ionic liquids consisting of a coordinating solvent and salt, that give rise to a chelate complex with very similar properties to ionic liquids.

On the Synthesis of [1,3]Azaphospholo[4,5‐f]quino(xa)lines and 2,3‐Dihydro‐[1,3]azaphospholo[4,5‐f]quino(xa)line 1‐oxides

European Journal of Organic Chemistry, Volume 28, Issue 17, May 21, 2025.
Syntheses of quinoline and quinoxaline derivatives fused with phosphacycles were developed from commercially available quinolin‐6‐amine and quinoxalin‐6‐amine. Abstract Despite their potential in areas such as medicinal chemistry and organic materials, scaffolds in which quinoline and quinoxaline are fused to phosphacycles such as 1,3‐oxaphosphole, 1,3‐

New Cytotoxic Derivatives by the Phosphorylation and Phosphinoylation of Diethyl α‐Amino‐α‐Aryl‐Methylphosphonates

Chemistry – A European Journal, Volume 31, Issue 21, April 9, 2025.
In order to make available potentionally bioactive new α‐aminophosphonic derivatives, diethyl α‐amino‐α‐aryl‐methylphosphonates were phosphorylated, phosphinoylated and thiophosphinoylated with the corresponding P‐chloride. The effect of a P=O to P=S modification was evaluated by single crystal X‐ray cristallography.
