   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Photochemistry; Predissociation; Phenyl halides; Excited states; Substituent effects; Pump-probe spectroscopy; Molecular beam; Dynamics; Kemi; Chemistry; Kemi;

   Sammanfattning : We have studied fundamental aspects of photo-induced dissociation kinetics and dynamics in several phenyl halides. By combining femtosecond pump-probe measurements with ab initio calculations we are able to account for several observations. LÄS MER

3. 2. [11C]Carbon Monoxide in Rhodium-/Palladium-Mediated Carbonylation Reactions

   Sammanfattning : Methods for the 11C-labeling of carbonyl compounds applicable in the preparation of radiotracers for Positron Emission Tomography (PET) are described. To this end [11C]carbon monoxide at low concentration was used in transition metal- mediated reactions. LÄS MER

4. 3. Coordination chemistry of late transition metals with PCP ligands. Synthesis, catalysis and mechanism

   Författare :Daniel Olsson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organometallic chemistry; Metallorganisk kemi; Organic chemistry; Oorganisk kemi; Inorganic chemistry; Suzuki reaction; Stille reaction; catalysis; cyclometalation; C-H activation; PCP complex; POCOP ligand; PCP ligand; iridium; palladium; platinum;

   Sammanfattning : Abstract The work presented in this thesis discusses synthesis of PCP-complexes and utilisations of such organometallic compounds in catalysis. The complexes, obtained by intramolecular Csp3-H activation, are based on the metals palladium, platinum and iridium. LÄS MER

5. 4. Design and synthesis of steroid mimetic libraries using solid phase techniques

   Författare :Marcus Ruda; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Pyridone; quinolone; benzoindazole; solid phase chemistry; scavenger resin; combinatorial chemistry; alpha-arylation; nuclear hormone receptor; steroid mimetic.;

   Sammanfattning : This thesis deals with the design and synthesis of biologically active ligands for nuclear hormone receptors using combinatorial techniques. In the first part, a 5,6,6a,7,8,9,10,10a-octahydrobenzo[f]quinolin-3(4H)-one tricyclic core structure was designed mimicking the ABC-rings of a steroid. LÄS MER
