| Abstract: | Nucleophilic addition the title compound by alkoxide ions (OR?) at 0°C proceeds via a red intermediate probably involving metal-nucleophile interaction, and subsequent formation of the carboalkoxy compound C7H9Fe(CO)2(CO2R). On raising the temperature, the latter compound rearranges spontaneously by a dissociative mechanism to give the corresponding 5-exo-ring compound C7H9ORFe(CO)3. |
