1. Polymer Bound Water-Soluble Metal Phosphine Complexes-Preparation, Characterisation and Catalytic Application
Abstract : Four new water-soluble phosphines have been prepared by utilising water-soluble polymers as charge carrying units. Coupling of methyl-4-(diphenylphosphino)-benzyl-amine or 4-diphenylphosphino benzaldehyde to poly-acrylic acid and poly-ethylene imine, respectively, afford the ligands PAA-PNH and PEI-PNH. READ MORE

2. A Catalytic and Mechanistic Investigation of Palladium-Phosphine Catalysed Aqueous Hydroxycarbonylation. Steric and Electronic Properties of the Ligands
Abstract : The steric and electronic properties of eight water-soluble phosphines (1-8) were investigated by different methods. Phosphines 1-6 were tested as ligands in palladium catalysed hydroxycarbonylation of styrene. READ MORE

3. Transition metal-catalysed enol formation from allylic alcohols : Isomerisation, C−C and C−F bond formations
Abstract : This thesis describes the isomerisation of allylic alcohols into enols and enolates catalysed by transition metal complexes. The transformation has been used to prepare both unsubstituted and α-substituted carbonyl compounds. Significant attention has been given to the mechanistic aspects of the reactions. READ MORE
