Synthesis of Novel 4(3H)-Quinazolinones with 1,2,3-Triazoles Moiety Conjugated by Schiff Base

Synthesis and characterization of some novel 1,2,4-triazoles, 1,3,4-thiadiazoles and Schiff bases incorporating imidazole moiety as potential antimicrobial agents.

(1,4,5-Triphenylimidazol-2-yl-thio)butyric acid hydrazide (3) was obtained via alkylation of 1,4,5-triphenylimidazol-2- thiol (1) with ethylbromobutyrate, followed by addition of hydrazine hydrate. Treatment of acid hydrazide 3 with carbon disulfide in an ethanolic potassium hydroxide solution gave the intermediate potassium dithiocarbazinate salt, which was cyclized to 4-amino-5-[(1,4,5-triphe...

Synthesis and Characterization of Novel Lead (II) Complexes with Schiff Base Iminopyridine Ligand

First, Schiff base iminopyridine ligand has been prepared by the condensation between primary amine, dimethylaniline and active carbonyl group of pyridine carboxaldehyde, then related complexes were synthesized in methanol solution. The ligand and metal complexes have been characterized by elemental analysis, UV, IR, 1 H NMR and 13CNMR spectroscopy. The spectroscopic data of metal complexes ind...

Ion-induced tubular assembly of conjugated Schiff-base macrocycles.

“ Synthesis and Study of Schiff base Ligands ”

The new Schiff bases are synthesis from various and aldehyde and amine under magnetic stirrer method .The synthesized Schiff base were characterized by spectral techniques (UV-Spectra & IR-Spectra). And the Schiff base are yellow colour solid and having sharp melting point and insoluble in organic solvents.
