Gold complexes for homogeneous cross-coupling catalysis and migratory insertion reactions
Most of the different homogeneous reactions catalyzed by gold have been developed in the past fifteen years and stem from the ability of both Au(I) and Au(III) complexes to coordinate and activate multiple carbon-carbon bonds. However, the high ionization potential of gold has long hindered Au(I)/Au...

| Sumario: | Most of the different homogeneous reactions catalyzed by gold have been developed in the past fifteen years and stem from the ability of both Au(I) and Au(III) complexes to coordinate and activate multiple carbon-carbon bonds. However, the high ionization potential of gold has long hindered Au(I)/Au(III) catalytic cycles under homogeneous conditions, an underdeveloped field compared to classical cross-coupling methodologies. Although direct evidence for the main elementary steps of organometallic chemistry has been obtained very recently, their scope is still limited and much remains to be done before our knowledge on gold reaches that of other transition metals, especially of groups 9 and 10. Therefore, the unifying motivation behind the different research topics presented in this doctoral dissertation is to enhance our expertise concerning the factors governing the reactivity of gold complexes, with oxidative addition and migratory insertion particularly under the spotlight |
