To get inside the properties of N,N-disubstituted Schiff bases, we synthesized three high-yielding benzaldehyde Schiff bases. We used the reaction between salicylaldehyde and different diamine compounds, including diamine, ethanediamine, and o-phenylenediamine, determining the structure of obtained molecules by nuclear magnetic resonance spectroscopy and electrospray ionization mass spectroscop...

Novel comb-like cuprous oxide nanorod-based structures were synthesized through an interface etching method with salicylaldehyde as ligand and reducing agent in a water-toluene system and were demonstrated to have great application potentials as ethanol sensors.

The polarographic behaviour of salicylaldehyde-2-pyridylhydrazone (SAPH) has been studied in aqueous buffer solution containing 40% ethanol using DC and DP polarographic methods. In the pH range 1.8--7.5 the observed single irreversible reduction wave is assigned to the splitting of the N N bond and reduction of C = N centre. In alkaline medium, a second wave appears at a more negative potentia...

A hydroxoiridium complex coordinated with 1,5-cyclooctadiene efficiently catalyzed the hydroacylation of bicyclic alkenes with 2-hydroxybenzaldehyde and its derivatives in high yields with high stereoselectivity.

The synthesis of 2-deoxyfortimicins A (15) and B (11) and 1-deamino-2-deoxy 2-epi-aminofortimicins A (18) and B (12) is described. Two routes have been developed for synthesis of the key intermediate 2-O-methanesulfonylfortimicin B (7). One route involves selective blocking of fortimicin B with N-benzyloxycarbonyl groups followed by formation of a 4,5-salicylaldehyde oxazolidine derivative. Sub...

Larvae of the leaf beetle subtribe Chrysomelina sensu stricto repel their enemies by displaying glandular secretions that contain defensive compounds. These repellents can be produced either de novo (iridoids) or by using plant-derived precursors (e.g. salicylaldehyde). The autonomous production of iridoids, as in Phaedon cochleariae, is the ancestral chrysomeline chemical defence and predates ...

Rhodococcus sp. strain TFB is a metabolic versatile bacterium able to grow on naphthalene as the only carbon and energy source. Applying proteomic, genetic and biochemical approaches, we propose in this paper that, at least, three coordinated but independently regulated set of genes are combined to degrade naphthalene in TFB. First, proteins involved in tetralin degradation are also induced by ...

The reactions of ruthenium trichloride with Schiff bases derived from sulpha drugs in 1:2 molar ratio leads to the formation of a new series of coordination compounds of type [Ru(L) 2 (H 2 O)Cl]. The Schiff bases used here are o-Vanillin sulphanilamide (oVSaH), o-Vanillin sulphamerazine (oVSmrzH), salicylaldehyde sulphanilamide (SdSaH), salicylaldehyde sulphamerazine (SdSmrzH), 2-hydroxy-1-naph...

In the title compound, C(14)H(11)N(3)O(2), the dihedral angle between the mean planes of the benzotriazole ring system and the benzene ring of the salicylaldehyde group is 2.4 (2)°. There is an intra-molecular O-H⋯N hydrogen bond which may influence the mol-ecular conformation.
