On August 1, 2022, Dabrowska, Aleksandra M.; Mech-Warda, Paulina; Wera, Michal; Domzalska, Marta; Makowski, Mariusz; Chylewska, Agnieszka published an article.Quality Control of N-((4-Aminophenyl)sulfonyl)acetamide The title of the article was Prototropic tautomerism of (E)-N-((4-((2-hydroxy-5-methoxybenzylidene) amino)phenyl)sulfonyl)acetamide and its coordination abilities towards Ru, Rh, and Ir trivalent metal ions. And the article contained the following:
The Schiff base (E)-N-((4-((2-hydroxy-5-methoxybenzylidene)amino)phenyl)sulfonyl) acetamide (ScB-SAM) has been synthesized bytheir condensation at room temperature in ethanol. X-ray crystallog. anal. revealed that the keto-enol tautomerism of its solid state exists as a complex equilibrium system that is stabilized intramol. hydrogen bond. The enol, keto and mixed enol-zwitterionic forms were observed in the crystal structure. The crystallog. results were supported by ATR, and UV-Vis. Phys. properties were determined in different polar and nonpolar solvents and solid state. All above exptl. results were then compared with DFT calculations Addnl., the stabilities of the trivalent: iridium, rhodium and ruthenium ions complexes with ScB-SAM have also been investigated by spectrophotometric titration methods in water. The data showed that the examined coordination compounds were stable in solution based on the values of their stability constants found. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).Quality Control of N-((4-Aminophenyl)sulfonyl)acetamide
