Organosilver species in transmetallations

Combining the mild nucleophilicity of alkynylsilvers with the halogenophilicity of silver ions suggests their use in transmetallation reactions. 

This idea led to only a few reactions with alkynylsilver species, although such processes certainly occurred in various catalyzed reactions (see Sections 10.4,10.5.1, 10.5.2, 10.5.4.1, 10.6.4, and Ref. 8). 

In the nucleophilic opening of oxiranes by silver acetylides (see Section 10.4), Koide et al. provided good evidence for transmetallation of silver acetylides to dichlorozirconocene leading to alkynyl zirconium species.98
