The title compound, C21H23NO4S, obtained by alkaline treatment of 1,5-bis(1-phenoxy)-3-azapentane at moderate heating, is a N-tosylated secondary vinylamine. An intramolecular S=O...H—C hydrogen bond generates a 13-membered ring. The benzalacetone moiety adopts a trans conformation with respect to the C=C double bond, which is slightly longer than usual due to the conjugation with a neighbouring acetyl group. Theoretical predictions of potential biological activities were performed, suggesting that the title compound can inhibit gluconate 2-dehydrogenase (85% probability), as well as to act as a mucomembranous protector (73%).

A new lead(II)-organic architecture [Pb(HL) (dipyrido[3,2-a:2′,3′-c]phenazine (dppz))](H2O)2 (1) was successfully prepared under hydrothermal conditions by using organic-acid linker 5-((4-carboxyphenoxy)methyl) benzene-1,3-dioic acid (H3L) and N-donor chelating ligand dppz.

Densities, ρ123, and speeds of sound, u123, of 1-methyl pyrrolidin-2-one (1) + benzene or methyl benzene or cyclohexane (2) + propan-2-ol (3) ternary mixtures have been measured over the entire composition range at 308.15 K and atmospheric pressure.

The association constants for a series of methylbenzene-fluoranil electron donor-acceptor complexes have been determined from NMR chemical shift measurements using 1: 1 stoicheiometric ratios of electron donor-electron acceptor. The resulting values differ from those obtained when large excess concentrations of donor are used. It is suggested that the differences may be the result of the presence of significant concentrations of termolecular complexes in the latter solutions.

One of the main challenges that virgin olive oil producers face today is an accurate prediction of the sensory quality of the final product prior to the milling of the olives. The possibility that olive paste aroma can be used as a predictive measurement of virgin olive oil quality is studied in this paper. The study was centered on distinguishing the aroma of olive pastes that produced virgin olive oils without sensory defects from the aroma of olive pastes the virgin olive oils of which showed sensory defects. Olive pastes were analyzed by solid-phase microextraction-gas chromatography and a sensor system based on metal oxide sensors. Forty-four volatile compounds were identified in olive pastes, all of them being also present in virgin olive oil. Six volatile compounds - acetic acid, octane, methyl benzene, (E)-2-hexenal, hexyl acetate and 3-methyl-1-butanol - distinguished both kinds of pastes with only five misclassified samples. Five metal oxide sensors were able to classify the olive pastes with only two erroneous classifications.
