Metal complexes of a novel Schiff base derived from sulphametrole and varelaldehyde. Synthesis, spectral, thermal characterization and biological activity

Spectroscopy, Crystal and Molecular Structures of New 4-Acylpyrazolone Dinitrophenylhydrazones

“…Their versatile behavioral properties, remarkable reactivity and wide applications still continue to attract a lot of research attention [1,2]. They are synthesized easily by way of a condensation reaction between a carbonyl group (aldehydes or ketones) and an amine in a basic system with the elimination of water molecules as a by-product [3,4]. Acylpyrazolones have been reported to be a very useful chemical compound [5][6][7][8] and they form interesting Schiff bases on reaction with different amine groups by way of functional group substitution and synthetic modifications [9,10].…”

Crystal structure of N′-(5-bromo-2-methoxybenzylidene)-3- methylbenzohydrazide, C16H15BrN2O2

“…Schiff bases play an important role in biological [1][2][3] and coordination chemistry [4][5][6]. Recently, we have reported the crystal structures of afew Schiff bases and their complexes with metal atoms [7,8].…”
