“…The diffraction data were collected on a Bruker D8 Venture photon diffractometer using graphite monochromated Mo Ka radiation (λ = 0.71073 Å). The structure was solved by direct methods using the SHELXL-2015 and SHELXL-2017 (Sheldrick, 2015 and Sheldrick, 2017) programs [17]. All of the non-hydrogen atoms were refined anisotropically and the hydrogen atoms were included in geometric positions but not refined.…”

A novel Schiff base 2, 2'-((1E,1'E)-((4-methyl-1, 3-phenylene) bis (benzylidene)) bis (methylethylidene)) bis (4-methoxyphenol) (L) was the result of the reaction between 2, 4diaminotoluene and 2-hydroxy-5-methoxy benzaldehyde. The compound (L) was characterized using IR, UV-Vis, 1 H, and 13 C NMR techniques. The structure of the ligand was determined by X-Ray Diffraction method (XRD). All experimental results were proved and explained theoretically exploiting DFT (Density Functional Theory) calculations. The electrochemical properties were studied through the cyclic voltammetry and the results were explained by the mean of the FMOs (Frontier Molecular Orbitals). The antioxidant activity of the synthesized Schiff base was evaluated by utilizing several tests as DPPH (1, 1-diphenyl-2picryl hydrazyl), ABTS (2, 2'-azino-bis(3-ethyl benzthiazoline-6-sulfonicacid), hydroxyl radical scavenging test, reducing power test, β-carotene bleaching test as chemical methods, and the superoxide radical scavenging as electrochemical method. The effective concentration (EC 50 ) showed that the compound has a good antioxidant activity, and the relationship between the structure-activity and the calculated electronic properties demonstrates that the compound has a good reactivity.

Coumarins are an important class of natural heterocyclic compounds that have attracted considerable synthetic and pharmacological interest due to their various biological activities. This review emphasizes on the synthetic methods for the preparation of dialkyl 2-oxo-2H-1-benzo- pyran-3-phosphonates and alkyl 1,2-benzoxaphosphorin-3-carboxylates. Their chemical properties as acceptors in conjugate addition reactions, [2+2] and [3+2] cycloaddition reactions are discussed.
