1. 1. 2-Hydroxypyridine-Ligated Pd-complexes as pre-catalysts in Hydrogen Borrowing Chemistry α -Alkylation of Ketones Using Alcohols

   University essay from Lunds universitet/Kemiska institutionen

   Author : Ayesha Kanwal; [2017]
   Keywords : Hydrogen Borrowing in activation of alcohols; Palladium in Catalysis; hydrogenation and dehydrogenation reactions; hydrogen borrowing concept for hydrogenation and dehydrogenation reactions; 2-hydroxyquinoline Ligand; 2-hydroxy pyridine ligands; inorganic chemistry; oorganisk kemi; Chemistry;

   Abstract : An efficient method for selective alpha-alkylation of ketones with alcohols was developed using 2-hydroxypyridine-based ligands coordinated by palladium as pre-catalysts. The reactions were performed without additional additives under mild reaction conditions. The method is environmentally friendly to build C-C bond as water is the only byproduct. READ MORE

3. 2. Towards Nickel Boride Catalyzed C-C Coupling Reactions

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Ágnes Lakó; [2017]
   Keywords : heterogeneous catalysis; nickel catalysis; coupling reactions; cross-coupling; homocoupling;

   Abstract : This thesis focuses on the study of nickel boride as a catalyst in various coupling reactions. The nickel boride catalyst was investigated in three different coupling reactions, the experiments aimed at understanding the activity and catalytic properties of nickel boride. READ MORE

4. 3. X-Ray Photoelectron Spectroscopy of Metal & Metal-based Clusters: Au, Ag & Sn Cases.

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

   Author : Charles Wright; [2016]
   Keywords : Physics; Photoelectron; Spectroscopy; Cluster; Clusters; Gold; Silver; Tin; Synchrotron; X-Ray; Physics and Astronomy;

   Abstract : Clusters are particles which consist of a finite number (2 − 10 ^6−7 ) of atoms/molecules. For the work presented in this thesis free clusters have been produced in order to study their properties, free of interfering substrates, using photoelectron spectroscopy at the MAX-lab synchrotron facility in Lund, Sweden.

5. 4. Synthesis and Reactivity of N-heterocyclic Gold (I) Complexes

   University essay from Lunds universitet/Kemiska institutionen

   Author : Lars Erik Andreas Ehnbom; [2013]
   Keywords : Oorganisk kemi; inorganic chemistry; Chemistry;

   Abstract : Populärvetenskaplig sammanfattning Metallorganisk kemi är en gren av kemin som fokuserar på att utveckla nya reaktioner med hjälp av övergångsmetaller som t.ex. järn, kobolt och guld. Genom att använda övergångsmetaller i kemi är det möjligt att bilda nya reaktioner som man med konventionell organisk kemi inte kan få tillgång till. READ MORE

6. 5. Synthesis and Reactivity of (PCNMe) Pincer Palladium Complexes

   University essay from Lunds universitet/Kemiska institutionen

   Author : Abdelrazek Mousa; [2013]
   Keywords : oorganisk kemi; inorganic chemistry; Chemistry;

   Abstract : New (PCNMe) pincer Pd(II) complexes were synthesized and their properties were studied in various reactions. (PCNMe)Pd-Br was synthesized and employed as catalyst for Suzuki cross-coupling reactions of aryl halides (e.g. bromobenzene, 4-bromotoulene and 4-bromobenzaldehyde) with phenylboronic acids (e.
