2. 1. Formation and Decomposition of Platinum–Thallium Bond, Kinetics and Mechanism. Structural Characterization of Some Metal Cyanides in the Solid State

   Author : Péter Nagy; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal–metal bond; platinum; thallium; kinetics; mechanism; stopped flow; oxidative addition; cyano complexes; edta; redox reaction; metal cyanides; X–ray diffraction; Raman; NMR; mercury; palladium; nickel; one dimensional wire;

   Abstract : The kinetic and mechanistic features of a new series ofplatinum-thallium cyano compounds containing a direct andunsupported by ligands metal-metal bond have been studied insolution, using standard mix–and–measurespectrophotometric technique and stopped–flow method.These reactions are interpreted as oxidative addition of the cspecies to the square planar Pt(CN)42-complex.

5. 3. Mössbauer studies of electron population in some iron complexes

   Author : Ulf Helgeson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mössbauer-effekten;

   Abstract : A Mössbauer effect measuring system has been constructed. With the use of a liquid helium cryostat measurements are performed at room liquid nitrogen and liquid helium temperature. A superconducting magnet with fields up to 5 Tesla has been used in the cryostat. READ MORE

6. 4. Compounds with Non-Buttressed Metal-Metal Bond between Platinum and Thallium. Model Systems for Photoinduced Two-Electron-Transfer

   Author : Mikhail Maliarik; KTH; []
   Keywords : thallium; platinum; cyanide; metal-metal bond; non-buttressed; heterometallic; photoinduced; electron transfer; redox reaction; NMR; chemical shift; spin-spin coupling constant; Raman; EXAFS; X-ray diffraction; equilibrium; oxidation state; oxidative;

   Abstract : A new family of oligonuclear cyano compounds incorporatingtransition (Pt) and main group (Tl) metals bound with anon-buttressed Pt-Tl bond was synthesised in aqueous solution.The metal-metal linkage is formed in the reaction betweenplatinum and thallium in their stable oxidation forms, Pt(II)and Tl(III), orvice versa: Pt(IV) and Tl(I).

7. 5. Synthesis and structure activity relationship studies of non-nucleoside HIV-1 reverse transcriptase inhibitors

   Author : Marita Högberg; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Organic Pharmaceutical Chemistry; organisk farmaceutisk kemi;

   Abstract : HIV-1 reverse transcriptase (RT) is a target for anti-HIV chemotherapy. A series of PETT PhenylEthylThiazoleThiourea) non-nucleoside HIV-1 RT inhibitors were synthesised. All compounds were tested in an HIV-1 RT enzyme assay, and in cell culture using MT-4 cells and wild-type virus. READ MORE
