TL;DR: In this paper, 5-bromo-2-acetyl benzofuran with hydrazine followed by condensation of the resulting hydrazone with different quinoline derivatives gave the corresponding Schiff bases.
Abstract: Treatment of 5-bromo-2-acetyl benzofuran with hydrazine followed by condensation of the resulting hydrazone with different quinoline derivatives gave the corresponding Schiff bases. Reaction of these Schiff bases with thioacetic acid furnished the target thiazolidinone molecule. Some of the newly synthesized compounds show promising analgesic and antimicrobial activity.

TL;DR: In this paper, a tautomeric hydrazone mixture was obtained as a mixture of E and Z isomers according to n J (15 N, 13 C), and a comparison of the 1 H NMR data with GIAO DFT calculations enabled determination of the configuration of the carboxy ester group in both isomers.

TL;DR: In this article, a series of nickel(II) chelates of stoichiometry M(MeOBhC6H4X)2 were characterized and the pyridine and 1,10-phenanthrolinc adducts of the complexes were characterizcd.
Abstract: A series of monoligand nickel(II) chelates Ni(SalC6H4X) · 3 H2O containing salicylaldehyde aroylhydrazones H2SalC6H4X were isolated and characterized. The correspondingo-methoxyhenzaldcliyde aroylhydrazones (HMeOBhC6H4X) react with nickel(II) acetate to give isomeric red and green chelates of stoichiometry M(MeOBhC6H4X)2. The red isomers were assumed to possess a square planar arrangement with the hydrazone molecule acting, as a mononegative bidentate ligand, whereas an octahedral structure was assigned to the green isomer with the hydrazone molecule acting as mononegative tridentale ligand. The pyridine and 1,10-phenanthrolinc adducts of the complexes were characterizcd.
