2. 1. Catalysis in Dynamic Systems: Control within Molecular Reaction Networks

   Author : Fredrik Schaufelberger; Olof Ramström; Leonard Prins; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; systems chemistry; dynamic covalent chemistry; catalyst screening; reaction networks; organocatalysis; imine exchange; combinatorial chemistry; dynamic systemic resolution; feedback; error-correction; Morita-Baylis-Hillman reaction; C-H activation; H-bond catalysis; transamination; Kemi; Chemistry;

   Abstract : Life as we know it is based on complex networks of biochemical reactions that constantly interact within large dynamic systems. The field of systems chemistry uses chemical models to study how reaction networks – and thereby life – function on a molecular level. READ MORE

4. 2. Dynamic Systems : Enzymatic Synthesis, Exchange Reactions and Applications in Materials Science

   Author : Yang Zhang; Olof Ramström; Mihail D. Barboiu; KTH; []
   Keywords : constitutional dynamic chemistry; reversible reactions; kinetic resolution; dynamic kinetic resolution; enzyme catalysis; lipase; asymmetric synthesis; racemization; oxazolidinone; organogel; enamine; nitroaldol reaction.;

   Abstract : This thesis is divided into three parts, revolving around the developments of dynamic systems utilized in dynamic kinetic resolution (DKR) and constitutional dynamic chemistry (CDC).The first section gives an introduction to constitutional dynamics, the core concept of this thesis.

5. 3. Ruthenium-catalyzed hydrogen transfer involving amines and imines : Mechanistic studies and synthetic applications

   Author : Joseph S M Samec; Jan-E Bäckvall; Jack R. Norton; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

   Abstract : This thesis deals with ruthenium-catalyzed hydrogen transfer involving amines and imines and is divided into two parts. In Part 1 a mechanistic study has been performed. READ MORE

6. 4. Polyhydroxyl and Polyphosphorylcholine functionalized Silica for Hydrophilic interaction liquid Chromatography- Synthesis, characterization and application

   Author : Nhat Thi Hong Bui; Knut Irgum; Michael Lämmerhofer; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrophilic Interaction Chromatography; HILIC; silica; TRIS; acrylamide acrylate; ATRP; iniferter; “controlled living’’ radical polymerization; N; N′-methylenebisacrylamide; MPC; stationary phase; analytisk kemi; Analytical Chemistry;

   Abstract : This thesis focuses on the development of new stationary phases for use in hydrophilic interaction liquid chromatography using TRIS-based and phosphorylcholine typed monomers and porous silica particles as starting substrates. In this thesis, several ways of polymerizing highly hydrophilic mono­mers onto pore surfaces of silica supports are described, based on several “grafting from” schemes. READ MORE

7. 5. Mechanistic Studies on Ruthenium-Catalyzed Hydrogen Transfer Reactions

   Author : Jenny B. Åberg; Jan-Erling Bäckvall; Charles P. Casey; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; mechanistic studies; catalysis; ruthenium; hydrogen transfer; racemization; transfer hydrogenation; alcohols; ketones; amines; imines; inner-sphere; outer-sphere; solvent cage effect; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

   Abstract : Mechanistic studies on three different ruthenium-based catalysts have been performed. The catalysts have in common that they have been employed in hydrogen transfer reactions involving alcohols and ketones, amines and imines or both. READ MORE
