Synthesis, spectroscopic and electrochemical characteristics of a novel Schiff-base from saccharin and tryptophan

Abstract

In the present work, a novel Schiff-base was synthesized by the reaction of saccharin with tryptophan and characterized by elemental analysis as well as UV-Vis, FT-IR, 1 H NMR spectroscopic data. The voltammetric behavior of Schiff-base was also studied on the hanging mercury drop electrode (HMDE) by using Square-Wave Voltammetry (SWV) and Cyclic Voltammetry (CV) techniques. The voltammograms of the Schiff-base exhibited two irreversible reduction peaks in Britton-Robinson buffer (pH 7.0-10.0) for the potential range from 0.0 V to -1.4 V. These peaks which appeared at more positive potentials than the reduction peaks of tryptophan and saccharin, may be assigned to the cathodic reductions of C-N + and >C=N-moieties of Schiffbase.

Experimental and computational investigation on the corrosion inhibition characteristics of mild steel by some novel synthesized imines in hydrochloric acid solutions

“…The use of chemical inhibitors has been acknowledged as one, and a very practical and most economical, method of combating corrosion amine and a carbonyl group, having wide applications in many biological aspects, proteins, visual pigments, enzymic aldolization and decarboxylation reactions [16,17]. An interesting application of Schiff's bases is their use as effective corrosion inhibitors, which is based on their ability to spontaneously form a monolayer on the surface to be protected [18].…”

Article 32

“…Schiff bases are organic compounds containing the azomethine group and have shown useful applications in biological, analytical, photochemical, electrochemical, theoretical and in structural studies Olalekan et al, 2016;Patterson et al, 2014;Çakır and Biçer, 2010;Radecka-Paryzek et al, 2007). They are also used as catalysts in polymer and dye industries and have been used for immobilization of enzymes (Boghaei et al, 2008;Prashanthi, 2008).…”

Electrochemical Reduction of Isatin-monohydrazone on Mercury Electrode

“…Electrochemical methods are very favorable to obtain this information and successfully used to the redox behavior of various biological compounds. [22][23][24][25][26][27][28][29] The hydrazones are electroactive compounds. In the literature, there are many published works on the electrochemical reduction of azo and hydrazone compounds.…”
