Testo completoThe present study deals with the synthesis and characterization of six tri-palladium complexes code named MH3, MH4, MH5, MH6, MH7 and MH8 that contained two planaramine ligands bound to the central or each of the terminal metal ions. The activity of the compounds against human cancer cell lines: A2780, A2780cisR and A2780ZD0473R, cell uptake, levels of DNA-binding and nature of interaction with salmon sperm and pBR322 plasmid DNA have also been determined. Whereas cisplatin binds with DNA forming mainly intrastrand GG adduct that causes local bending of a DNA strand, the tri-palladium complexes are expected to bind with DNA forming a number of long-range interstrand GG adducts that would cause a global change in DNA conformation. Among the designed complexes, MH6 that has two 2-hydroxypyridine ligands bound to each of the two terminal palladium ions is found to be most active. The compound also has the highest cell uptake and Pd-DNA binding levels. In contrast, MH8 which has two 4-hydroxypyridine ligands bound to each of the two terminal palladium ions is found to be least active. The results indicate that, as applied to the terminal metal centres, 2-hydroxypyridine would be more activating than 4-hydroxypyridine perhaps because of greater protection provided to the terminal centres from coming in contact with the solvent molecules. In contrast, when bound to the central metal centre, 4-hydroxypyridine appears to play a slightly greater activating role than 2-hydroxypyridine or 3-hydroxypyridine, suggesting that non-covalent interactions such as hydrogen bonding associated with the ligand rather than its steric effect may be a more important determinant of antitumour property. The results illustrate structure-activity relationships and suggest that the tri-palladium complex containing two 2-hydroxypyridine ligands bound to each of the three metal centres or the compound that contains two 2-hydroxypyridine ligands bound to each of the two terminal metal centres and two 4-hydroxypyridine ligands bound to the central metal centre, may be much more active than any of the designed complexes.

Testo completo-diimine Pd(II) complexes having a functionalized hydrocarbon attached to the imino nitrogen was performed. The catalytic activity of these complexes were then evaluated in the polymerization of ethylene and in the Heck coupling reaction of methyl acrylate with iodobenzene.
Unconjugated &beta
-diimine complexes of palladium were also synthesized and their activities towards ethylene polymerization and the Heck coupling of methyl acrylate and iodobenzene also evaluated and compared to that of the &alpha
-diimine complexes. Three of the &alpha
-diimine complexes synthesized showed activity towards ethylene polymerization, these being the complexes bearing the allyl, styrene and phenol functionalities. &omega
-Carboxylato complexes which were also synthesized showed no activity towards ethylene polymerization.
The polymer produced was found to be high density linear polyethylene with an average PDI of 2.54 with Mn values ranging between 3.42 and 6.90 x 10-5 and Mw values ranging between 6.05 and 17.6 x 10-5.
The complexes bearing the allyl, styrene and phenol functionalities, as well as the &omega
-carboxylato complexes active in the Heck coupling reactions of methyl acrylate with iodobenzene. None of the unconjugated &beta
-diimine complexes prepared showed any activity towards ethylene polymerization even at high Al/Pd ratios. The activity of these complexes towards the Heck arylation reaction was comparable to that of the &alpha
-diimine complexes showing similar activities.

Testo completoThis dissertation describes the development of various palladium-catalyzed syntheses of organoboron compounds with the 1,2-metallate shift of organoboron “ate” complexes as a common mechanistic feature. Chapter one discusses the history of the 1,2-metallate shift with a focus on reactions promoted by transition metals, followed by my work on the palladium-catalyzed, enantioselective, halide-tolerant conjunctive cross-coupling reaction to enable the use of Grignard reagents and arylbromides. Chapter two discusses the attempt to engage allylic electrophiles in the conjunctive cross-coupling reaction and the discovery and optimization of the vinylidenation reaction to access 1,1-disubstituted boryl alkenes. Unlike other palladium-catalyzed reactions that proceed by a 1,2-metallate shift, the vinylidenation proceeds by a β-hydride elimination rather than a reductive elimination as the final step in the catalytic cycle. Chapter three discusses the development of the enantioselective conjunctive cross-coupling of propargylic electrophiles to access enantioenriched β-boryl allenes. Methanol additive was found to improve both the yield and enantioselectivity of the reaction. 1H NMR studies show that methanol exchanges with the pinacol ligand on the boron “ate” complex

Testo completoDostert, Karl-Heinz. "Selectivity in hydrogenation of alpha, beta-unsaturated carbonyl compounds on model palladium catalysts". Doctoral thesis, Humboldt-Universität zu Berlin, Mathematisch-Naturwissenschaftliche Fakultät, 2015. http://dx.doi.org/10.18452/17399.
Testo completoThe conversion of alpha,beta-unsaturated aldehydes and ketones with hydrogen over model Pd catalysts was investigated using molecular beam techniques combined with infrared reflection-absorption spectroscopy (IRAS), quadrupole mass spectrometry (QMS), and near-edge X-ray absorption fine structure (NEXAFS) studies under well-defined ultra-high vacuum conditions. The aim of this work was to gain atomistic-level understanding of structural factors governing the selectivity and activity of a Pd(111) single crystal and iron-oxide-supported Pd nanoparticles for C=C and C=O bond hydrogenation. The ketone isophorone and the aldehyde acrolein were chosen as prototypical alpha,beta-unsaturated carbonyl compounds. NEXAFS and IRAS studies showed that isophorone is adsorbed on Pd(111) in a flat-lying geometry at low coverages. With increasing coverage, both C=C and C=O bonds tilt with respect to the surface plane. The tilting is more pronounced for the C=C bond on pristine Pd(111), indicating a strong distortion of the conjugated pi system upon interaction with Pd. Co-adsorbed hydrogen leads to a conservation of the in-plane geometry of the conjugated pi system, pointing to a much weaker interaction of isophorone with Pd in the presence of hydrogen. The selective partial hydrogenation over a Pd(111) surface and supported Pd nanoparticles with different particle sizes was investigated using acrolein. Molecular beam techniques were combined with IRAS and QMS measurements in order to simultaneously monitor the evolution of surface species and the formation of the final gas-phase products. Over a Pd(111) single crystal, acrolein is hydrogenated at the C=O bond to form propenol with nearly 100% selectivity, while over supported Pd particles, selective conversion of the C=C bond to propanal occurs. IRAS investigations showed that a distinct modification of the Pd(111) surface with a dense overlayer of an oxopropyl species is required for propenol formation.

Testo completoIntramolecular Wacker-type cyclization of unsaturated polyols and aminopolyols represents a powerful method in the synthesis of oxygen- or nitrogen-containing heterocycles. The thesis offers an insight into the systematic study of domino intramolecular palladium(II)-catalyzed cyclization and coupling reaction allowing the implementation of side chains into heterocyclic skeletons along with the formation of two stereocenters in a single step. Different types of coupling partners and reaction conditions were examined, the influence of substrate substituents on diastereoselectivity is discussed. The applications in the synthesis of naturally occuring compounds or their analogs are outlined (anisomycin, varitriol). Palladium(II)-catalyzed oxycarbonylation represents an interesting transformation of unsaturated polyols into bicyclic lactones with tetrahydrofuran structural motif with excellent cis-stereoselectivity. The first example of the use of ionic liquids as reaction media in the asymmetric Pd(II)-catalyzed oxycarbonylation is described. Based on a ligand screening, the chiral bis(oxazoline)-type ligands were successfully used in the Pd(II)-promoted bicyclisationof racemic pent-4-ene-1,3-diol (±)-69a. The kinetic resolution of (±)-69a in the presenceof chiral catalyst and p-benzoquinone under carbon monoxide atmosphere using acetic acid and/or ionic liquid as solvent afforded enantioenriched 2,6-dioxabicyclo[3.3.0]octane-3-ones(R,R)-70a (57% ee) and (S,S)-70a (80% ee), respectively
