2. 1. Methodological studies in solid phase synthesis : Linkers and applications of multi-component condensations

   Author : Mikael Erlandsson; Anders Undén; Thomas Norberg; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Solid phase peptide synthesis; solid phase organic chemistry; linkers; self-scavenging; safety catch linker; cyclic peptides; reductive acidolysis; disulfides; reduction; metallic zinc; multi-component condensations; combinatorial chemistry; Neurochemistry; Neurokemi;

   Abstract : Solid phase synthesis has become an increasingly important tool in the synthesis of oligopolymers and small organic molecules. This thesis covers three important areas in the solid phase synthesis technique: linker strategies, reduction methods and novel routes to complex heterocycles. READ MORE

4. 2. Numerical simulation of multi-scale transport processes and reactions in pem fuel cells using two-phase models

   Author : Munir Khan; Jinliang Yuan; Bengt Sundén; Värmeöverföring; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical analysis; multi-scale; multi-phase; reacting flows; multi-component;

   Abstract : A numerical study for the cathode of a PEM fuel cell has been performed in this study. The results have been limited to cathode only because, in PEM fuel cells, the oxygen reduction reactions, ORRs, are considered the rate limiting reactions and govern the fuel cell performance.

5. 3. Organocatalytic Transformations with N-Heterocyclic Carbenes - An Investigation of Ionic Liquids as NHC Precatalysts and Aerobic Oxidative Esterifications

   Author : Linda Ta; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; N-heterocyclic carbene; ionic liquid; multi-component reaction; aerobic oxidation; OTHO; Organocatalysis; green chemistry;

   Abstract : The call for more sustainable processes in the chemical society has led to the development of the field of green chemistry. The Twelve Principles of Green Chemistry serve as guidelines for the design of processes. READ MORE

6. 4. Applications of multi-component condensations and development of polyamine synthesis on solid-phase

   Author : Daniel Jönsson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurochemistry and Neurotoxicology; neurokemi och neurotoxikologi;

   Abstract : Solid-phase synthesis of small non-polymeric molecules has become increasingly important as a tool in the development of pharmacologically active compounds. Of particular interest are the syntheses of compounds with low molecular weight, low polarity and a reduced flexibility of the functional groups, i.e. READ MORE

7. 5. Catalytic Functionalization of Allylic Substrates by Palladium Pincer Complexes

   Author : Nicklas Selander; Kálmán Szabó; David Milstein; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Catalysis; Palladium; Pincer Complex; Boron; Multicomponent Reaction; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

   Abstract : This thesis is based on the development of novel catalytic reactions for the synthesis and application of organometallic reagents. The main focus is directed towards organoboronate derivatives. We developed an efficient procedure for converting allylic alcohols to the corresponding allylboronates using palladium pincer complexes as catalysts. READ MORE
