Alkyl Lewis Acid Catalyzed Syntheses of Dicarbonyl Ferrocenes

Abstract

A series of diferrocenoyl compounds; succinyl (1), glutaryl (2), adipoyl (3), suberoyl (4) and sebacoyl ferrocene (5) were synthesized from the reaction of ferrocene with EtAlCl₂. Compared to the conventional methods reported in the literature, the yields obtained from these reactions are found to be higher than the typical catalyst.
