A series of (κ2-N,O)-salicylaldiminato Ni(II)-methyl pyridine complexes 7-pyr and 8-pyr derived from 3,5-diiodosalicyaldehyde (3a) and 3-(9-anthryl)salicylaldehyde (3b), and terphenylamines 2,6-(3,5R-4-R′-C6H2)2C6H3-NH2 (4a, R ) CF3, R′ ) H; 4b, R ) tBu, R′ ) H; 4c, R ) tBu, R′ ) OH; 4d, R ) Me, R′ ) H; 4e, R ) Me, R′ ) MeO; 4f, R ) MeO, R′ ) H; 4g, R ) MeO, R′ ) MeO), was prepared by reaction ...

Post-synthesis modification is a useful method for the functionalization of metal-organic frameworks (MOFs). A novel catalyst Au@MIL-101-ED-SA (ED = ethylenediamine, SA = salicylaldehyde), containing coexisting Au3+ ions and Au⁰ nanoparticles, was prepared successfully by post-synthesis modification with ethylenediamine, salicylaldehyde and gold. Gold nanoparticles supported on MIL-101 (Au@MIL-...

Three Schiff's bases AI (2(1-hydrazonoethyl)phenol), AII (2, 4-dibromo 6-(hydrazonomethyl)phenol) and AIII (2(hydrazonomethyl)phenol) were prepared as new hydrazone compounds via condensation reactions with molar ratio (1:1) of reactants. Firstly by reaction of 2-hydroxy acetophenone solution and hydrazine hydrate; it gives AI. Secondly condensation between 3,5-dibromo-salicylaldehyde and hydra...

Incorporation of fluorene groups into the salicylidene moiety significantly enhances the luminescence of a number of multinuclear alkynylated Zn(II)-salophen complexes. Preparation of these complexes was achieved by a synthetic strategy with facile handling of the reactants, simple purification of the products, and one-pot reaction process. Two synthetic methods are used for the preparation of ...

a series of schiff bases of ni(ii) and cu(ii) using acetylacetone (acac), salicylaldehyde (sal), ethylenediamine (en), and o-phenylendiarnine (dabe) were prepared and characterized. the electronic spectra of some copper chelates in various organic solvents depend strongly on the solvent used and the d-d band of cu(ii) shifts to red with the increase of the donor number (dn) of solvent. the colo...

An efficient and environmentally friendly procedure for one-pot synthesis of 13-acetyl-9-methyl-11-ox-8-oxa-10,12-diazatricyclo [7.3.1. ] trideca-2,4,6-triene from salicylaldehyde, acetylaceton and urea via Biginelli condensation and intramolecular Michael-addition by using magnesium bromide as an expensive and easily available catalyst under solvent-free condition is desired. The structural el...
