Synthesis , characterization and antimicrobial activity of shiff and mannich bases of uracil derivatives [PDF]

open access: yesKirkuk Journal of Science, 2016
In the present work some Shiff bases (1a,b,c,d)were syuthesized using phenyl alanine with aniline by microwave irradiation. Aseries of mannich base (2a,b,c,d) were prepared by the reaction of (1a,b,c,d) with uracil in the presence of formaldehyde.The ...

Fluorescence and UV-Visible Analysis of some Synthesized Imine Compounds Derived from 4,4'-Sulfonyldianiline

open access: yesActa Chimica Slovenica
Five imine derivatives were subsequently synthesized by condensation of 4,4'-sulfonyldianiline with substituted aromatic aldehyde or ketone in the presence of p-TsOH/EtOH. They are namely 4,4'-sulfonylbis(N-(2,4-dinitrobenzylidene)aniline) (C1), 4,4'-(4,

Synthesis of Some Imines and Investigation of their Biological Activity

open access: yesE-Journal of Chemistry, 2009
Some N-benzylidene aniline derivatives have been synthesized and tested as antibacterial agents. The results of the in vitro tests showed that most of the synthesized compounds were antibacterial inactive against E.coli.

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts

open access: yesAdvanced Materials, EarlyView.
An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

open access: yesAdvanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.
