  2. 1. Multicomponent Catalytic Reactions : Theoretical and Experimental Studies

    Author : Martin Pauze; Enrique Gomez Bengoa; Belen Martin-Matute; Vincent Gandon; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; C-H Activation; Quaternary Quinolinium; Organocatalyst; Transition Metal Catalyst; Umpolung Strategy; Multi-step Reactions; Mechanistic Investigation; Density Functional Theory; organisk kemi; Organic Chemistry;

    Abstract : In this thesis, Density Functional Theory (DFT) methods have been applied to study the mechanisms of three different multicomponent organic reactions. Also, a new synthetic procedure for the preparation of quinolinium salts is presented, and its mechanism also studied by DFT calculations. READ MORE

  4. 2. Palladium(0)-Catalysed Carbonylative Multicomponent Reactions : Synthesis of Heterocycles and the Application of Quinolinyl Pyrimidines as Enzyme Inhibitors

    Author : Linda Åkerbladh; Mats Larhed; Luke Odell; Anders Karlén; Lise-Lotte Gundersen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Palladium catalysis; Carbonylation; Multicomponent reactions; Domino reactions; Heterocycles; 4-Quinolones; 2-Aminoquinazolinones; Benzoxazinones; N-Acylguanidines; Type II NADH dehydrogenase; NDH-2;

    Abstract : Palladium-catalysed carbonylative multicomponent reactions have proven useful for the synthesis of structurally diverse compounds. Carbon monoxide serves as an atom-efficient, one-carbon building block, which allows for further structural elaboration of the carbonyl compound. READ MORE

  6. 4. 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

  7. 5. Elucidating Chemical and Electrochemical Side-Reaction Mechanisms in Li-ion Batteries

    Author : Neeha Gogoi; Erik Berg; M. Rosa Palacín; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion battery; solid electrolyte interphase; electrolyte additives; reaction mechanism; ethylene carbonate; vinylene carbonate; tris trimethylsilyl phosphate; surface enhanced Raman spectroscopy; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Lithium-ion batteries constitute a leading technology that plays a major role in the transition towards sustainable transportation and power generation. The stability of modern batteries relies on a passivation layer formed on the negative electrode known as the solid electrolyte interphase (SEI). READ MORE
