Abstract: This thesis deals with the synthesis of cyclopentadienyl-functionalised N-heterocyclic carbenes and its coordination to both middle and late transition metals. One of the goals was to gain chemical knowledge on the reactivity patterns of these complexes, and explore their potential applications in catalysis. The imidazolium salts synthesised in the course of this thesis represent a series containing changes in the electronic and steric parameters. The ligand precursors were coordinated to molybdenum, ruthenium, rhodium and iridium. These organometallic complexes were studied in homogeneous catalysis processes such as: olefin epoxidation (Mo), isomerisation of allylic alcohols (Ru), b-alkylation of alcohols, Nalkylation of amines and transfers hydrogenation of ketones (Ir).(...)
