Gas-phase synthesis of [Ag4H] and its mediation of the C-C coupling of allyl bromide

Abstract

Collision-induced dissociation (CID) of silver-amino acid clusters results in the formation of the silver hydride cluster [Ag4H]+, which mediates C-C bond coupling of allyl bromide (see scheme). Energy-resolved CID experiments reveal that the product is 1,5-hexadiene and suggest analogies between the chemistry of the clusters and that of silver surfaces and nanoparticles.
