“…34 On the other hand, there are many reported studies, which showed effective antioxidant properties of Schiff bases in the literature. [35][36][37] In this paper, new Schiff base derivatives have been synthesized and all structures have been identified by using NMR, FTIR, and GC-MS techniques. In addition, in situ catalytic activities for Suzuki cross-coupling reactions and the antioxidant activities via DPPH (2,2-diphenyl-1-picrylhydrazyl) and Ferrous ions (Fe 2+ ) chelating methods have been examined for all synthesized molecules.…”

New series of Schiff bases have been synthesized from the reaction between cyclohepta-2,4,6-trien-1-ylmethanamine and different aldehydes, and characterized via using 1 H NMR, 13 C NMR, FTIR spectroscopy, and GC-MS. After the successful synthesis, the in situ catalytic activity of all Schiff bases have been examined for the Suzuki C C cross-coupling reactions using phenylboronic acid, aryl bromides, and PdCl 2 as a catalyst. Before starting these investigations, reaction conditions were optimized using different bases and solvents. At the end of these reactions, the best efficiency was obtained in Et 3 N and EtOH. In addition to catalytic investigations, antioxidant activities of all synthesized Schiff bases were examined using DPPH and Iron (Fe 2+ ) chelation methods, and IC 50 values were calculated. While many molecules show various amounts of antioxidant activity, especially molecules 8e and 8g showed the best activity compared to butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA), which were used as positive controls, in DPPH and Iron chelating methods, respectively.

“…Synthesis of (Z)−1-(thiophen-2-ylmethyleneamino)propane-2-ol was synthesized by an existing procedure [19,20]. To a solution of thiophene-2carbaldehyde (0.10 mole, 9.30 mL) in 30 mL of benzene, a solution of 1-aminopropan-2-ol (0.10 mol, 8.30 mL) in 30 mL benzene was added with continuous stirring and refluxed by using a Dean-Stark, to remove the water produced, apparatus for 3 h at 60 • C. After examining the completion of the reaction by thin-layer chromatography, the product was cooled to room temperature and then filtered.…”

This study presents a new and rapid analytical high‐performance liquid chromatography coupled with a photodiode array detector method for determining nickel ion (Ni2+) complex with Schiff base (Z)‐1‐(thiophen‐2‐yl‐methyleneamino) propane‐2‐ol easily. The influence of pH, surfactant, and effect of mobile phase on the formation of the Ni‐(Z)‐1‐(thiophen‐2‐yl‐methyleneamino)propane‐2‐ol complex was studied and optimized. The results showed that the acidic condition (pH = 5) favors the complexation most. Triton X‐100 neutral surfactant was used for dissolving the Ni–complex synthesized. A mobile phase ratio of methanol:acetonitrile:water 70:20:10, v/v/v was taken as optimum. This approach allowed the analysis of Ni2+ ion with the limit of detection of 0.0349 ng/mL over the linear range of (0.1–250 ng/mL) and a relative standard deviation of < 2%. The developed method exhibited remarkable extraction recoveries for Ni2+ in various real water samples (tap water; 98.0%–99.8% and river water; 97.0%–98.7%) and alloys with recoveries of (nichrome; 85.2% and chromel; 88.4%). Moreover, this protocol was also applied for the quantitation of Ni2+ in real sewage samples at a concentration level of 0.256 ng/mL. The outcomes of the present work successfully revealed the apparent superiority of Schiff base (Z)‐1‐(thiophen‐2‐yl‐methyleneamino) propane‐2‐ol toward the practical removal of target Ni2+ under real‐world conditions.
