This thesis addresses the coordination chemistry and reactivity of
copper and gold complexes with a focus on the elucidation of (i)
the metal-mediated activation of -bonds and (ii) the migratory
insertion reaction. Both processes are of considerable importance
in organometallic chemistry, but remain elusive for Cu and Au
complexes. In this work, the author contributes significant
advances: The first -SiH complexes of copper are experimentally and
computationally characterized, yielding valuable insights into
-bond activation processes for copper. Evidence for a highly
unusual migratory syn insertion of unsaturated organic molecules
into the gold-silicon bond of silylgold (I) complexes is provided
and the corresponding mechanism identified. The intermolecular
oxidative addition of -SiSi, -CC and -CX (X=halogen) bonds with
molecular gold (I) complexes is studied in detail, effectively
demonstrating that this reaction, usually considered to be
impossible for gold, is actually highly favored, provided an
adequate ligand is employed. The use of small-bite angle bis
(phosphine) gold (I) complexes allows for the first time the
oxidative addition of -CC and -CX bonds for gold (I). These results
shed light on an unexpected reactivity pattern of gold complexes
and may point the way to 2-electron redox transformations mediated
by this metal, opening up new perspectives in gold catalysis.
