Abstract

Synthesis of the first representatives of mixed acyl(perfluoroacyl)ferrocenes, 1-acetyl-1'-(trifluoroacetyl)ferrocene (3a) and 1-propionyl-1'-(trifluoroacetyl)ferrocene (3b), by stepwise Friedel-Crafts acylation is described. A comparison of redox potentials of acetylferrocene, (trifluoroacetyl)ferrocene, and 3a as determined by cyclic voltammetry shows that the substitution effect is not purely additive.
