Synthesis and Spectral Studies of Ru(II) Carbonyl Schiff Base Complexes

Abstract

The synthesis and characterization of hexa co-ordinated ruthenium(II) complexes of the type [Ru(CO)(B)(L)] (where B = PPh3, AsPh3, py or pip and L = dibasic tetradentate Schiff base ligand) were synthesized from the reaction of [RuHCl(CO)(B)(EPh3)2] (where E = P, B = PPh3, py or pip, E = As, B = AsPh3)with different tetradentate ligands. The ligands were derived by the condensation of 5-chloro-4-methyl-2-hydroxy benzophenone with ethylenediamine, propylenediamine and o-phenylene-diamine in 1:1 molar ratio. All the compounds have been characterized by elemental analysis and spectral (FT-IR, UV-VIS and 1H-NMR) methods. An octahedral environment around Ru(II) ion has been tentatively proposed for all the complexes

Synthesis and Reactivity of Zr MOFs Assembled from PNNNP-Ru Pincer Complexes

“…t Bu 4 (L) and RuHCl­(CO)­(PPh 3 ) 3 were prepared following literature procedures. THF and 1,4-dioxane were degassed by sparging with ultrahigh-purity argon and dried via passage through columns of drying agents using a solvent purification system from Pure Process Technologies.…”

Polystyrene anchored ruthenium(II) complex catalyzed carbonylation of nitrobenzene and amines for the synthesis of disubstituted ureas

“…IR spectra show a stretching vibration for eCH 2 at 2918 cm -1 for the polymer bound ligand and its complex. The stretching vibration of C]N bond appeared at 1613 cm -1 for the polymer anchored imidazole ligand which is shifted to 1618 cm -1 in the metal complex, indicating the coordination of azomethine nitrogen to the metal [24,25]. Another band at 1319 cm -1 (in ligand) for CeN stretching is shifted to lower region in the metal complex [26].…”
