Many efforts have been devoted to the development of asymmetric catalysis because of the significant use of chiral compounds as intermediates of pharmaceuticals and advanced materials.[1] Amongst many ligands which have been tested, planar chiral ferrocenes ligands constitutes a privileged family of ligands for enantioselective catalysis.[2] We will disclose in this communication the synthesis of a new chiral N-(p-toluenesulfonyl)-containing ferrocenyl ligands and its coordination chemistry with Ru, Ir and Rh precursors yielding in some cases chiral at metal complexes. [3] Moreover, DFT calculations in order to better understand the nature and stabilities of these complexes will be presented. Additionally, preliminary evaluation of the different complexes as catalysts for the asymmetric transfer hydrogenation of ketones will also be disclosed.

N-Heterocyclic carbenes have found many applications in modern metal catalysis, due to the formation of stable metal complexes, and organocatalysis. Among a myriad of N-heterocyclic carbene metal complexes, gold complexes have gained a lot of attention due to their unique propensity for the activation of carbon-carbon multiple bonds, allowing many useful transformations of alkynes, allenes, and alkenes, inaccessible by other metal complexes. The present review summarizes synthetic efforts towards the preparation of chiral N-heterocyclic gold(I) complexes exhibiting C2 and C1 symmetry, as well as their applications in enantioselective catalysis. Finally, the emerging area of rare gold(III) complexes and their preliminary usage in asymmetric catalysis is also presented.
