Schiff bases functionalized with PPh2 and SPh groups and their Ni(II) and Pd(II) complexes: Synthesis, crystal structures and applications of a Pd complex for Suzuki–Miyaura Coupling

Schiff bases of 1′-hydroxy-2′-acetonaphthone containing chalcogen functionalities and their complexes with and (p-cymene)Ru(II), Pd(II), Pt(II) and Hg(II): Synthesis, structures and applications in C–C coupling reactions

“…Crystal data and structural refinements are given in Tables 2 and 3 respectively, are consistent with the earlier reports [13][14][15]. The order of E-C(alkyl/aryl) bond distances is S < Se < Te.…”

Synthesis, characterization, CT‐DNA binding and docking studies of novel selenated ligands and their palladium complexes

“…Chiral‐selenated Schiff base ( S ) ‐L 1 H was synthesized by condensation of this amine with 3,5‐di‐ tert ‐butyl‐2‐hydroxybenzaldehyde in dry methanol and the whole reaction was completed in 6 h at RT. This Schiff base ( S ) ‐L 1 H on reduction with sodium borohydride in dry ethanol following the procedure reported earlier 33 resulted in a new chiral‐selenated reduced Schiff base ligand ( S ) ‐L 2 H . The progress of both of the reactions of ligands syntheses were monitored by TLC using an appropriate solvent system.…”

Copper(II) complexes of hydroxyflavone derivatives as potential bioactive molecule to combat antioxidants: synthesis, characterization and pharmacological activities

“…Flavones constitute one of the major classes of naturally occurring products. Synthesis of flavones and their derivatives has attracted considerable attention owing to their significant biocidal, [13] pharmaceutical [14] and antioxidant [15] activities. It has been observed that the presence of hydroxyl groups at position 5 or 7 is frequently required for higher biological activities.…”
