Two diepoxides containing a two-benzene-ring-conjugated Schiff base when cured with an aromatic diamine result in high-performance thermosets combining excellent controlled degradability, stability and antibacterial properties. Epoxy resins have been wide
Recyclable and Malleable Epoxy Thermoset Bearing Aromatic Imine Bonds
Zhao, Shou,Abu-Omar, Mahdi M.
, (2018/12/14)
A method for preparing reprocessable epoxy thermoset is presented. The process is composed of synthesis of a bisphenol monomer bridged by an imine bond, glycidylation of the bisphenol, and cross-linking with a hardener to form thermoset. The resulting epo

Three new series of biologically active amino substituted Schiff bases with general formula, R1N=CHR2. Here R1 = 2-amino-benzthiazole, 4-amino-salicylic acid and 4-aminophenol. R 2=4-chloro-benzaldehyde, 2-chloro-benzaldehyde, salicylaldehyde, vanillin and benzaldehyde were synthesized by the reaction of three different amino substituted compounds and substituted aldehydes in ethanol. Such compounds were characterized by different physico-chemical techniques like, melting point, elemental analysis, multinuclear nmr (1H, 13C). The free ligands and their metal complexes have been screened for their in vitro biological activities against bacteria, fungi and yeast. The metal complexes show more potent activities compared with Schiff base ligands.
Evaluation of antibacterial activity of some Schiff bases

experimental part, p. 1338 - 1342 (2010/08/05)
From 4-amino phenol, some Schiff bases were synthesized. By IR and NMR spectral data, the structural characterization of these synthesized compounds were done. The antibacterial activity of all these synthesized Schiff bases was studied against B. cereus-ATCC 11778, P. aero-ATCC 27853, E. coli-ATCC 25922, K pneu-NCIM 2719 and 5. aureus-ATCC 25923, by agar ditch method in dimethyl formamide and dimethyl sulfoxide. It is observed that antibacterial activity depends on the molecular structure of Schiff base, solvent used and bacterial strain under consideration. Out of two solvents studied, dimethyl formamide is proved to be best and salicylaldehyde as side chain to 4-amino phenol could be used as lead molecule in drug designing i.e. in inhibiting above bacterial strains.

This synthesis of imines has been carried out efficiently by the condensation of carbonyl compounds with amines in the presence of silica gel supported sodium hydrogen sulfate (NaHSO4.SiO2) as a heterogeneous catalyst under microwave irradiation in solvent-free conditions. NaHSO4.SiO2 can be recovered and re-used up to ten times by simple washing with diethyl ether after each use and activated in an oven at 120°C for 1 h, thus rendering the process more economical.
Magnesium perchlorate as an efficient catalyst for the synthesis of imines and phenylhydrazones
Chakraborti, Asit K.,Bhagat, Srikant,Rudrawar, Santosh
, p. 7641 - 7644 (2007/10/03)
Magnesium perchlorate has been found to be an efficient catalyst for the synthesis of imines and phenylhydrazones by the reaction of carbonyl compounds with amines and phenylhydrazine in high yields at room temperatures and in short times. The condensation of less electrophilic carbonyl compounds with poorly nucleophilic amines affords the imines in excellent yields.
