contrast, related arene rutheniumcomplexes prepared from benzyl acetoacetate and phenethyl acetoacetamide failed to undergo spirocyclization, but were found to participate in intramolecular SNAr reactions (leading to formation of tetralone and benzazepinone ring systems, respectively). Thus, the conformational mobility of the side chain linking the nucleophilic center to the coordinated arene ring
