1. Ligand Dependent Regioselectivity in Palladium Mediated Allylic Alkylation
Abstract : In this thesis, different aspects on ligand dependent regioselectivity in palladium mediated allylic alkylation have been studied. It is believed that the regioselectivity is a result of nucleophilic attack trans to phosphorous when applying ligands wih different donor atoms. READ MORE

2. Catalytic Functionalization of Allylic Substrates by Palladium Pincer Complexes
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

3. Palladium(II)-Catalysed Heck and Addition Reactions : Exploring Decarboxylative and Desulfitative Processes
Abstract : Palladium complexes have the ability to catalyse cross-coupling of two organic moieties through the formation of transient metal-carbon bonds, thus bringing them closer to each other to facilitate the formation of a new bond. Palladium-catalysed coupling reactions are one of the most important carbon-carbon forming reactions available to organic chemists and many of these reactions rely on the reactivity of aryl-palladium complexes.

4. PEPPSI-type Complexes of Palladium and Platinum: : Investigation of Properties and Applications in Catalysis
Abstract : Catalysis is a powerful tool to highly efficient production of desired newchemicals by acceleration of a chemical reaction rate. Special compounds used forthis purpose are called catalysts; they induce a change in the chemicalenvironment without being consumed during the process. READ MORE

5. Synthesis of Nanoparticles and Organometallic Complexes for Gas Sensing
Abstract : Currently metal nanoparticles (NPs) are a subject of interest regarding many applications, in particular chemical gas sensing, as the associated environmental issues are of substantial importance. Metal NPs are attractive due to their fascinating optical properties and primarily, localized surface plasmon resonance (LSPR) which strongly depends on size and shape of NPs. READ MORE
