Nonconventional Friedel-Crafts Chemistry. VII. On Homoannular and Heteroannular Reactions of Ferrocene with Bifunctional Moieties under Friedel-Crafts Conditions
The utilization of ferrocene in the organic synthesis and its uses in Friedel-Crafts chemistry, together with our interest in this area, prompted us to investigate the reaction of ferrocene with halo acid chlorides and α,β-unsaturated acid chlorides under different Friedel-Crafts conditions with the aim to employ these reactions in the syntheses of polycyclic ferrocene derivatives.
