The advantageous properties of the Cp * ligand - intensified electron donation, steric bulk, and enhanced solubility in comparison to the ubiquitous Cp ligand - are finding increasing use in organometallic chemistry. A systematic evaluation of synthetic routes to pentamethylferrocene compounds with a wide range of functionalities, including carboxyl, carbonyl, aminomethyl, vinyl, ethynyl, fulvenyl, cyclopentadienylmethyl, and others is reported. Spectroscopic, structural, and electrochemical properties of such functionalized pentamethylferrocenes Fc * /2-R are compared to those of non-methylated ferrocenes Fc-R. The electronic influence of the Cp * ligand in these unsymmetrical ferrocenes Fc * /2-R has been studied by cyclic voltammetry measurements, demonstrating a decrease in oxidation potential of -0.276V in direct comparison to non-methylated ferrocenes Fc-R.
