Influence of substituent effects on the coordination ability of salicylaldehyde Schiff bases

Additional effect of para‐hydroxyl on the reduction potentials of theN‐benzylidenebenzenamines

“…Also the results of this paper are consistent with the experimental facts reported. For example, the reduction of compounds containing 4‐OH‐ArCHN structure and other X‐ArCHN structure by NaBH 4 , the former takes longer than the latter under the same reduction conditions, that is, the former is more difficult to be reduced.…”

“…Schiff bases are a kind of important organic compounds containing CN double bond. They are not only widely used as ligand in coordination chemistry but also are able to be converted into various amines by reducing their molecular CN double bond to CH–NH single bond . For examples, Jia et al employed sodium tetrahydroborate (NaBH 4 ) to reduce the imine CN double bond of ruthenium (II) p ‐cymene complexes containing Schiff‐base ligands [Ru(p‐cymene)LCl] and prepared half‐sandwich ruthenium complexes, which have active catalysts.…”

Tan et al used NaBH 4 to reduce the imine CN double bond in the synthesis of novel 3‐(1,3,4‐thiadiazolyl)‐1,3‐bezoxazines, which have fungicidal activity. Liu et al synthesized 4‐[(5‐aryl‐1,3,4‐thiadiazol‐2‐ylamino)methyl]phenol compounds via the nucleophilic addition reaction of 5‐aryl‐1,3,4‐thiadiazol‐2‐amine with 4‐hydroxybenzaldehyde and the reduction of CN double bond in the presence of NaBH 4 reducing agent.…”

Crystal structure of bis{5-chloro-2-(((4-trifluoromethyl)imino)methyl)phenolato-κ2 N,O}copper(II), C28H16Cl2CuF6N2O2

“…So far, we have synthesized a series of bidentate Schiff base copper complexes [8]. Particular attention has been paid to the structural and spectroscopic properties of Schiff base metal complexes [9,10]. In the title crystal structure, the coordination sphere of Cu atom is found to be formed by two bidentate ligands.…”

Fluorimetric Detection of Zn2+, Mg2+, and Fe2+ with 3-Hydroxy-4-Pyridylisoquinoline as Fluorescent Probe

“…As a result, the development of sensitive and selective optical probes, also named chemosensors, for cation detection has attracted much attention in recent years [5][6][7][8][9][10]. Specifically, the development of sensitive and easyto-use fluorimetric probes for biologically abundant metal cations, such as Zn 2+ and Fe 2+ , has a special importance as imbalances in their levels may lead to serious health problems [11][12][13][14][15][16][17][18][19]. To this end, numerous fluorescent ligands, whose emission changes signficantly on cation complexation, have been developed and employed for the detection of metal ions in biological and environmental samples [5][6][7][8][9][10].…”
