Abstract

In homogeneous transition metal catalysis, coordinat1vely highly unsaturated complexes are often assumed to play a vital
role, but are rarely stable as such and are normally generated from suitable precatalysts. During my PhD studies, I have
employed N·heterocyclic carbene (NHC) ligands for the synthesis or unsaturated, yet isolable [(NHC)lr(COD))'" complexes.
When employed 1n lhe mtramolecular hydroammat1on these ((NHC)lr(CODW species show very high catalytic activity under
mild react on conditions. An enantiopure version of the catalyst system produces pyrrolidines with excellent enantioselectivities.
A serendipitous discovery led to the isolation of chloride-bridged Ir-Ag adducts during the attempted synthesis of these cations.
