The research focuses on the synthesis, characterization, and evaluation of organometallic palladium and platinum complexes with strongly donating alkyl coligands. The study explores the chemical and cytotoxic properties of complexes [(COD)M(R)X] and [(COD)M(R)(R)] (where COD = 1,5-cyclooctadiene, M = Pd or Pt, R = various alkyl groups, and X = halogen). The experiments involved transmetallation reactions to introduce alkyl coligands and subsequent ligand exchange reactions to incorporate alkynyl coligands. The reactants included Grignard reagents, organolithium derivatives, stannanes, and silver or thallium salts. The synthesized complexes were characterized using multinuclear NMR and IR spectroscopy, and in some cases, X-ray diffraction (XRD) was used to collect structural data. The cytotoxicity of selected complexes was assessed against HT-29 and MCF-7 tumor cells, with some complexes showing high cytotoxicity. The research provides insights into the binding properties of ligands to platinum or palladium and contributes to the potential development of new anti-tumor agents.
This research focused on the systematic synthesis and characterization of mixed-metal clusters involving rhenium and various platinum metals, specifically focusing on octanuclear carbido clusters. The purpose of the study was to explore the isolobal analogy between cyclopentadienyl (Cp-) and the [Re7C(CO)21]3- framework, and to understand how different MLn+ caps affect the electronic characteristics of these compounds. The researchers synthesized a series of new mixed-metal clusters with the general formula [Re7C(CO)21MLn]2-, where MLn+ included Rh(CO)2, Rh(CO)(PPh3), Rh(COD), Ir(COD), Pd(C3H5), Pt(C4H7), and Pt(CH3)3 (COD = 1,5-cyclooctadiene; C3H5 = v3-allyl; C4H7 = q3-(2-methyl)allyl). The study concluded that the [Re7C(CO)21]3- unit can support a variety of capping units, suggesting that reactions such as ligand substitution and oxidative addition might occur at the capping metal center without disrupting the cluster framework. The research also demonstrated the direct interconversion of Re7C(CO)213- and Re8C(CO)242-, shedding light on possible pathways of cluster growth.
The study investigates the discontinuous pressure effects on the enantiodifferentiating photosensitized isomerization of cyclooctene and cycloocta-1,5-diene, sensitized by chiral benzene-1,2,4,5-tetracarboxylates. The purpose of the study was to understand how hydrostatic pressure up to 750 MPa influences the enantiomeric excess (ee) of the (E)-isomer produced, indicating a switch in the enantiodifferentiation mechanism due to conformational changes in the chiral auxiliaries. The chemicals used included (Z)-cyclooctene, (Z,Z)-cycloocta-1,5-diene, and chiral benzene-1,2,4,5-tetracarboxylates (3a–c) as chiral sensitizers. These sensitizers served to induce the isomerization process and were crucial in examining the pressure's effect on asymmetric photosensitization, which could be useful for controlling product chirality and ee.
The research focuses on the synthesis and characterization of palladium(II) and platinum(II) metal complexes with iminophosphine ligands. The purpose of this study was to investigate the coordination behavior of iminophosphines towards palladium(II) and platinum(II) and to evaluate the potential of these complexes as catalysts in Heck and Suzuki cross-coupling reactions, which are significant in modern synthetic organic chemistry for the formation of carbon-carbon bonds. The researchers synthesized new complexes by reacting N-(2(diphenylphosphino)benzylidene)(phenyl)methanamine and N-(2-(diphenylphosphino)(benzylidene)(thiophen-2yl)methanamine with MCl2(cod) and MCl(cod)Me (M = Pd, Pt; cod = 1,5-cyclooctadiene), resulting in complexes such as [M(Ph2PPhNHCH2-C5H4N)Cl2] and [M(Ph2PPhNHCH2-C4H3S)Cl2]. The synthesized compounds were characterized using various analytical techniques including 31P-, 1H-NMR, IR spectroscopy, electro spray ionization mass spectrometry (ESI-MS), and elemental analysis. The study concluded that the palladium complexes showed catalytic activity in both Suzuki and Heck coupling reactions, particularly with aryl bromides containing electron-withdrawing substituents, while the platinum(II) iminophosphine complexes 1b and 2b did not exhibit catalytic activity. The research provides valuable insights into the design of new catalysts for cross-coupling reactions and contributes to the understanding of the coordination chemistry of iminophosphine ligands with transition metals.
