Intermediates and Mechanisms of Gold(I)-Catalyzed Nucleophilic Addition Reactions
Generally, gold(I) complexes interact with pi-bonds of alkenes, alkynes and allenes to initiate nucleophilic addition reactions. As the key intermediates in these reactions, there has been recent interest in the synthesis and study of cationic, two-coordinate gold pi-hydrocarbon complexes. However, …

Catalytic C-N and C-F bond formation by organometallic group 11 complexes
… presents a study of the reaction between an (NHC)gold(I) fluoride complex (NHC = N-heterocyclic carbene) and alkynes (Chapter 1). Gold(I) and fluoride add trans across the triple bond of 3-hexyne and 1-phenyl-l-propyne to form (fluorovinyl)gold(I) complexes, with exclusive geminal arrangement …
