Asymmetric homogeneous catalysis forms one of the main planks of modern org
anic synthesis. It has developed rapidly and largely through the applicatio
n of novel ligands, whose design is very much based on insight and intuitio
n. At the same time, a better understanding of catalytic reaction mechanism
s can contribute to further progress, since it can identify the intimate re
lationship between ligand structure and successful applications. The presen
tation will concentrate an the author's research with complexes of the late
transition metals and include the search for superior methodologies in hyd
roboration, as well as ventures into the chemistry of reactive intermediate
s. The latter will be exemplified from work with rhodium and palladium cata
lysts.
