Abstract:
Transition metal complexes equipped with bidentate and polydentate ligands have found numerous applications in homogeneous catalysis. The use of functional polydentate ligands has contributed to the recent development of new catalytic processes and improvement of known reactions.We will show how proton responsive ligands can induce very attractive transformations. The unique role of chelating phosphinesulfonate ligands in nucleophilic allylic substitution, dehydrogenation of saturated cyclic amines into enamines followed by reaction with electrophiles, and enantioselective hydrogenation of aromatic ketones will be presented. The catalytic ability of phosphinepyridonate ruthenium and iridium complexes in hydrogenation of ketones and dehydrogenation of primary alcohols to produce acetals will be shown.
