Synthesis, Characterization, Computational and Biological Activity of Some Schiff Bases and Their Fe, Cu and Zn Complexes

open access: yesInorganics, 2022
Four new symmetrical Schiff bases derived from 2,2′-diamino-6,6′-dibromo-4,4′-dimethyl-1,1′-biphenyl or 2,2′-diamino-4,4′-dimethyl-1,1′-biphenyl, and 3,5-dichloro- or 5-nitro-salicylaldehyde, were synthesized and reacted with copper-, iron- and zinc ...

Biological applications of Schiff bases: An overview

open access: yesGSC Biological and Pharmaceutical Sciences, 2022
Schiff bases are the compounds containing the azomethine group (-HC=N-). They are formed by the condensation of ketones or aldehydes with a primary amine. Formation of Schiff base generally takes place under acid/base catalysis or with heat.

Addition of Di(trimethylsilyl) Phosphite to Schiff Bases of 2,5-Diformylfuran [PDF]

open access: yes, 2011
A series of 2,5-Furanyl-bis-(aminomethylphosphonic Acids) has been synthesized by the addition of di(trimethylsilyl) phosphite to azomethine bond of achiral Schiff bases derved from 2,5-diformylfuran.

Base-Free Synthesis and Photophysical Properties of New Schiff Bases Containing Indole Moiety

open access: yesACS Omega, 2022
Schiff bases represent an essential class in organic chemistry with antitumor, antiviral, antifungal, and antibacterial activities. The synthesis of Schiff bases requires the presence of an organic base as a catalyst such as piperidine.

Schiff bases: A short review of their antimicrobial activities [PDF]

open access: yes, 2011
Schiff bases are aldehyde- or ketone-like compounds in which the carbonyl group is replaced by an imine or azomethine group. They are widely used for industrial purposes and also exhibit a broad range of biological activities.

Coordination chemistry and bioactivity of Ni2+, Cu2+, Cd2+ and Zn2+ complexes containing bidentate schiff bases derived from S-benzyldithiocarbazate and the X-ray crystal structure of bis[S-benzyl-β-N-(5-methyl-2-furylmethylene)dithiocarbazato]cadmium(II). [PDF]

open access: yes, 2002
New bidentate isomeric NS and NS′ Schiff bases were derived from the condensation of S-benzyldithiocarbazate (SBDTC) with 5-methyl-2-furyldehyde and 2-furyl-methylketone.

Synthesis of 2-azetidinones substituted coumarin derivative [PDF]

open access: yes, 2012
α-Naphthol is converted into 4-methylbenzo[h]chromen-2-one by reacting with ethyl acetoacetate in the presence of bismuth trichloride which is then oxidized to 2-oxo-2H-benzo[h]chromene-4-carbaldehyde and then condensed with aromatic primary amines to
