synthesized. The structures of Schiff bases and their RuII‐p‐cymene complexes were elucidated using microanalysis, magnetic susceptibility, molar conductivity, 1H-NMR, 13C-NMR, FT-IR, UV–Vis, LC–MS, and thermogravimetric analysis techniques. Octahedral structures for the obtained RuII‐p‐cymene complexes were proposed. The catalytic activities of the RuII‐p‐cymene complexes obtained after the characterization
