The palladium(II) bis-chelate complexes of the type [Pd(TSC(1-5))2] (6-10), with their corresponding ligands 4-phenyl-1-(acetone)-thiosemicarbazone, HTSC(1) (1), 4-phenyl-1-(2'-chloro-benzaldehyde)-thiosemicarbazone, HTSC(2) (2), 4-phenyl-1-(3'-hydroxy-benzaldehyde)-thiosemicarbazone, HTSC(3) (3), 4-phenyl-1-(2'-naphthaldehyde)-thiosemicarbazone, HTSC(4) (4), and 4-phenyl-1-(1'-nitro-2'-naphtha...

Treatment of [{Ti(η5-C5Me5)(μ-NH)}3(μ3-N)] (1) with one equivalent of [Ni(cod)2] (cod = 1,5-cyclooctadiene) in toluene at 60–80 °C and subsequent addition of diphenylacetylene, trans-stilbene or triphenylphosphane afforded the nickel(0) complexes [LNi{(μ3-NH)3Ti3(η5-C5Me5)3(μ3-N)}] (L = PhCCPh (2), PhCH≡CHPh (3), PPh3 (4)). The nickel(II) complex [I2Ni{(μ3-NH)3Ti3(η5-C5Me5)3(μ3-N)}] (5) was pre...

Dithiocarbamates, with their high lipophilic character and good chelating properties, could provide stabile transition metal complexes enable these metal-based drugs to reach biological targets. Palladium(II) gold(III) complexes, due its structural similarity platinum(II)compounds, be competitive candidates for implementing developing new pharmacological agents. Herein, novel complex triammoniu...

An efficient one-pot synthesis of the cis-pyridylimine palladium (II) complexes is reported. The compo- sition and structure were proved by NMR, IR, X-ray, elemental analysis. monoamine oxidase inhibition activity synthesized complexes, including six previously unknown, inves- tigated on native mouse brains. Some compounds: cis-dichlorido-2,6-dimethyl-N- ((pyridin-2-yl)methylene)anilinepalladiu...

Nanoparticles of palladium-doped cerium oxide (Pd–CeO2) have been prepared by aqueous co-precipitation resulting in a single phase cubic structure after calcination according to X-ray diffraction (XRD). Inhomogeneous strain, calculated using the Williamson–Hall method, was found to increase with palladium content, and the lattice contracts slightly, relative to nano-cerium oxide, as palladium c...

The syntheses of nickel(II)porphyrins bearing palladium(II) or platinum(II) complexes at their periphery were performed. These new compounds characterized by standard spectroscopic techniques and studied electrochemistry. electrochemical data then compared with previously published porphyrin dimers linked metal ions like platinum(II). An X-ray structure one these species was obtained confirmed ...

A new fluorous PCP pincer ligand has been coordinated to Ni(II), Pd(II) and Pt(II). The air stable palladium complex, which promotes Heck reactions between methyl acrylate and either aryl bromides or iodides, can be recovered intact by fluorous solid-phase extraction and was reused four times in the Heck reaction between methyl acrylate and 4-bromoacetophenone without loss in catalytic activity.
