Abstract:
This book chapter discusses the effects of aurophilicity on gold catalysis. First, a brief historic account of aurophilicity in organogold chemistry is given, focusing on the pioneering results which set the stage for its association with catalytic intermediates (gold vinyl and gold aryl complexes); this is followed by an introduction to cationic gold(I) as an electrophilic catalyst, and the first isolation of organogold intermediates from catalysis. In the main section, the growing number of reports observing aurophilic interactions in catalysis or illustrative model systems is reviewed in a non-comprehensive tutorial way. The effects of aurophilicity are discussed in the following structures: (1) the geminal diauration of C(sp²)-atoms; (2) geminal diauration of other atoms; (3) σ-π-diauration of terminal alkynes. It is apparent that in most cases efficient catalysis is hindered by aurophilic effects as less active aggregates tend to be formed from more active species [LAu]⁺, but there are a growing number of reports using aurophilicity as a driving force to access new reactivity and selectivity.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
