The coordination of two 5-substituted-2,2?-bipyridines L (L1=5-methyl-2,2?-bipyridine, L2=5,5?-dimethyl-2,2? -bipyridine) to palladium was studied. The neutral complexes [Pd(L)Cl2] and [Pd(L)(Me)Cl], and the cationic complexes obtained after chlorine abstraction [Pd(L)2] [BAr?4]2 and [Pd(L)(Me)(NCMe)] [BAr?4] (Ar?=3,5- (CF3)2-C6H3), respectively, were isolated and characterized by NMR and FAB mass spectroscopy. The complex [Pd(L2)(L3)][BAr? 4]2 (L3=2,2? -bipyridine) bearing different ligands, was prepared for comparison purposes. The activity of the monocationic and dicationic complexes as catalytic precursors in the CO/4- tert -butylstyrene copolymerization was compared with that of related well-known catalysts containing the unsubstituted 2,2?-bipyridine as nitrogen ligand, to evaluate the influence of the substituents in 5- and 5,5?-position. The presence of one or two substituents on the nitrogen ligand has a positive effect on productivity using both types of precursors. No influence was observed on the polymer properties in terms of molecular weight and tacticity. Analysis of the reactivity of the methyl-palladium complexes towards carbon monoxide shows further differences depending on the nitrogen ligand.

New dineopentyl complexes of palladium, with the formula (L2 = dppe, bipy; L = PMe2Ph) have been prepared by the alkylation of the corresponding dichlorides with Mg(CH2CMe3)Br or LiCH2CMe3.Thermal decomposition of these complexes in solution yields 2,2,5,5-tetramethylhexane.The reactions of these compounds with CO and with some electrophiles (Ph3C+, PhCH2Br, HCl) have been investigated.The reaction with CO produces dineopentyl ketone (when L2 = dppe; L = PMe2Ph) or promotes rapid decomposition to 2,2,5,5-tetramethylhexane (when L2 = bipy).The electrophiles (E+) attack the neopentyl ligand to eliminate ECH2CMe3.In the reaction of with PhCH2Br, has been isolated.A palladacyclic analogue of these systems, , has been prepared by the alkylation of with Li(CH2CMe2CMe2CH2)Li.

Reaction of [PtCl2(cod)] (cod = cyclo-octa-1,5-diene) with either hippuric acid [PhC(O)NHCH2COOH] or N-phenylanthranilic acid (ortho-PhNHC6H4COOH) in refluxing dichloromethane in the presence of silver(I) oxide gave the new organoplatinum derivatives [Pt{N(COPh)CH2COO}(cod)] and [Pt{N(Ph)C6H4COO}(cod)] respectively.

Spectral and photophysical properties of mono and dinuclear Pt(II) and Pd(II) complexes: An unusual emission behaviour

Mononuclear complexes of the formula [M(N-N)(DHB)] and dinuclear complexes of the formula [M2(BPY)2(THB)] were synthesized and characterized. These complexes were found to show an optically active LLCT band and the platinum complexes of the series were found to show dual emitting states.

These complexes were characterized by chemical analysis, IR and proton NMR spectroscopy. A detailed study on the absorption spectroscopy of these complexes was made. These complexes were found to show a low-energy solvatochromic ligand-to-ligand charge-transfer (LLCT) band. The electronic energies of these bands have been analyzed and compared with electrochemical data. Emission behaviour of the complexes of the series, [Pt(N-N)(DHB)], [Pt(N-N)(DHBA)] {where DHBA is the dianion of 3,4-dihydroxybenzoic acid} and [Pt2(BPY) 2(THB)] was also investigated.

The neutral alpha-hydroxycarboxylate complexes [Pd(bpy)(GLYO)] ·3H2O (1), [Pd(bpy)(MANO)]·4H2O (2) and [Pd(GLYO)(phen)]·5H2O (3), together with the palladium(II) complexes [Pd(phen)2](NO3)2 (4) and [Pd(CH 2COCH3)(bpy)(Cl)] (5) (where GLYO and MANO are the glycolate and mandelate dianions, respectively, and bpy and phen, 2,2?-bipyridine and 1,10-phenantrholine, respectively), have been prepared by reaction of [Pd(bpy)Cl2] or [PdI2(phen)] with salts of alpha-hydroxycarboxylic acids in water. These compounds were characterized by elemental analysis, mass spectrometry, 1H and 13C NMR, UV-Vis, IR spectroscopy, TG analysis and single crystal X-ray diffraction. The aforementioned studies confirmed the formation of a variety of square-planar mononuclear compounds (1-3) where the alpha,alpha?-diimine ligands exhibit a rather simple bidentate chelating role and the alpha- hydroxycarboxylate ligands are dianionic. A variety of ligand distortions, hydrogen-bonding and stacking interactions were found and these were thoroughly analyzed. In compounds 1 and 3, the complex molecules are stacked in such a way that the coordination planes are parallel to one another. The Pd?Pd distances between the nearest stacked neighbors are 3.8043(6) and 3.302(2)/3.475(1) A?, respectively. Compounds 1-3 have been tested in vitro for cytotoxicity on HeLa-299 human tumor cell lines.

Synthesis and conformational studies of palladium(II) complexes containing [Ph2P(O)NP(E)Ph2]- (E=S or Se)

The ligands [Ph2P(O)NP(E)Ph2]- (E=S I; E=Se II) can readily be complexed to a range of palladium(II) starting materials affording new six-membered Pd-O-P-N-P-E palladacycles.

All compounds described have been characterised by a combination of multinuclear NMR [31 P{1 H} and 1 H] and IR spectroscopy and microanalysis. The molecular structures of five complexes containing the selenium ligand II have been determined by single-crystal X-ray crystallography. Three different ring conformations were observed, a pseudo-butterfly, hinge and in the case of all three PR3 complexes, pseudo-boat conformations. Within the Pd-O-P-N-P-Se rings there is evidence for pi-electron delocalisation.
