Palladium-Catalyzed Regio- and Stereoselective Arylesterification of Ferrocenylallene: A Synthetic Route to Ferrocene-Containing Disubstituted E-Allylic Esters
An efficient and concise protocol for the highly regio- and stereoselective synthesis of ferrocene-containing disubstituted E-allylic ester derivatives via a palladium-catalyzed intermolecular arylesterification reaction of ferrocenylallene with aryl iodides and carboxylic acids has been developed. The regio- and stereoselectivities of this reaction may be controlled by the steric effect of the bulky ferrocene group.
