Transition Metal Chemistry (Impact Factor: 1.4). 32(6):769-775. DOI: 10.1007/s11243-007-0247-x

ABSTRACT Synthesis procedures are described for the new stable mixed ligand complexes, [Pd(Hpa)(pa)]Cl, [Pd(pa)(H2O)2]Cl, [Pd(pa)(en)]Cl, [Pd(pa)(bpy)]Cl, [Pd(pa)(phen)Cl], [Pd(pa)(pyq)Cl], cis-[MoO2(pa)2], [Ag(pa)(bpy)], [Ag(pa)(pyq)], trans-[UO2(pa)(pyq)](BPh4) and [ReO(PPh3)(pa)2]Cl (Hpa = 2-piperidine-carboxylic acid, en = ethylene diamine, bpy = 2,2′-bipyridyl, phen = 1,10-phenanthroline, pyq = 2(2′-pyridyl)quinoxaline).
Their elemental analyses, conductance, thermal measurements, Raman, IR, electronic, 1H-n.m.r. and mass spectra have been measured and discussed. 2-Piperidine-carboxylic acid and its palladium complexes have
been tested as growth inhibitors against Ehrlich ascites tumour cells (EAC) in Swiss albino mice.

    ABSTRACT: A new polymer-anchored Pd(II) complex has been synthesized, characterized and its catalytic activity was investigated for the Suzuki cross-coupling reaction between aryl halides and arylboronic acid in the presence of K2CO3 as a base, for Heck olefination of aryl halides with alkenes, and for cyanation reaction of aryl iodides with K4Fe(CN)6 in presence of Et3N as base. The key features of the catalyst include rapid reactions with excellent conversion without the use of phosphine ligands and total stability under the reactions conditions. The catalyst was recovered by simple filtration and reused five-times without significant loss of catalytic activity.

    ABSTRACT: New complexes of 2-thione-4,6-diamino-5-hydroxypyrimidine (HTDAHP) with Fe(III), Ni(II), Ag(I) and Ru (II) are described. IR, 1H-NMR and mass spectra, conductivity, magnetic and thermal measurements of the complexes are reported and their structures discussed. HTDAHP behaves as a bidentate ligand, forming five membered hydroxyl-amino chelates or four-membered cyclic nitrogen-sulphur chelates without any participation of the pendant amino or hydroxy groups in complexation. The biological activities of the Ag(I) complexes against fungi (Aspergillus niger and Candida albicans) and bacteria (Staphylococcus aureus and Pseudomonas aeruginosa) have been investigated.

    ABSTRACT: A polymer-anchored Pd(II) Schiff base complex has been synthesized by reacting a polymeric amine with 2-pyridinecarboxaldehyde to get the polymer-anchored Schiff base, which was then reacted with palladium acetate. The catalyst was characterized by physicochemical and spectroscopic methods. It shows excellent catalytic activity in the Sonogashira coupling of phenylacetylene with aryl halides using triethylamine as a base and copper iodide as a co-catalyst in water under open air at 70 °C. We have also studied the effects of base and solvent on the coupling reaction. Sonogashira reactions of phenylacetylene with a variety of functionalized aryl halides were performed under the optimized reaction conditions. This catalyst gives excellent yields without the use of phosphine ligands. Further experiments showed that the catalyst can be used five times without much loss in the catalytic activity.
