Adsorption of styrene oxide on Ag(111) at 200 K leads to the formation of a stable oxametallacycle by ring opening of the epoxide. At elevated temperatures, the oxametallacycle reacts and the products desorb from the surface. We employ resonance enhanced multiphoton ionization time-of-flight mass spectrometry (REMPI-ToF-MS) to identify reaction products after desorption. We assign phenylacetaldehyde as the only product that desorbs at temperatures around 485 K.
