| Abstract | (η5-Chloroarene)- or (η6-nitroarene)(η5-cyclopentadienyl)iron hexafluorophosphates react readily with CF3CH2OH/K2CO3 or with piperidine or piperazine to give nucleophilic arom. substitutions with Cl or NO2 as the leaving group, further demonstrating an activation for SNAr reactions by complexation to the CpFe+ moiety. Similar nucleophilic arom. substitution reactions also occurred with carbanion-enolate anion nucleophiles derived from acetylacetone, di-Et malonate and Et acetoacetate, leading to the formation of C-C bonds. Pyrolytic sublimation of these SNAr reaction products could liberate the free substituted arene ligands, such as the synthetically useful di-Et phenylmalonate and Et α-phenylacetoacetate.
