文摘
Methylated ferrocenes are useful building blocks fornovel materials in molecularelectronics with advantageous properties in comparison to normalferrocene derivatives. Thepresence of nine, eight, or five methyl substituents leads to (i) adecrease in oxidationpotential, (ii) amplified donor capacity with correspondingly increasedstability of theferrocenium salts, and, most significantly, (iii) increased solubility.A modular syntheticapproach based on standard Wittig chemistry affords
