Synthesis of Metal Complexes of Some Formazans Obtaining From Cinnamaldehyde and Investigation of Their Dyeing Properties Using Different Methods

Abstract

In this study, two formazans were synthesized by coupling cinnamaldehyde phenyl hydrazone obtained by activation of cinnamaldehyde with phenylhydrazone, with diazonium salts of anthranilic acid and sulfonilic acid. The complexes of Co +2 , Ni +2 , Cu 2+ salts of these formazans were also synthesized. These compounds were characterized by elemental analysis, infrared (IR), ultraviolet-visible (UV-vis), 1 H nuclear magnetic resonance (1 H-NMR) and 13 C-NMR spectral data. Investigation of these compounds as dyes were studied. In the present experimental approach, two methods were employed; The first one was direct dyeing with these complexes, and the other one was complex formation on the fibres. Finally fastness values (test) were calculated and significantly higher values are obtained.

In Vitro and In Silico Antioxidant Activity of Hydrazones and Semicarbazones Derived from Aldehydes Found in Essential Oils

“…The preparation of the targeted hydrazones 1a-b and semicarbazones 2a-b was easily achieved. The four synthesized compounds were solid, and their yields, m.p., and NMR data are in accordance with the reference methods [18][19][20][21].…”
