Abstract

Silver hexynyl cluster cations, [(C₄H₉CCAg)_nAg]⁺, exhibit a rich unimolecular chemistry that is dependant on the cluster size, n (1–5), cluster fragmentation (for all n > 1); C–C bond coupling (n = 3 & 4); C–H bond activation with comcomitant silver hydride formation (n = 1 & 4); C–C bond activation (n = 1 & 4).
