A series of mono- and 1,1′-diheteroatom-substituted ferrocene derivatives as well as acylated ferrocenes was prepared efficiently by a unified strategy that consists of selective mono- and 1,1′-dilithiation reactions and subsequent coupling with carbon, phosphorus, sulfur and halogen electrophiles. Chem. oxidation of the ferrocene derivatives by benzoquinone, 2,3-dichloro-5,6-dicyanobenzoquinone, AgPF6, or 2,2,6,6-tetramethyl-1-oxopiperidinium hexafluorophosphate provided the corresponding ferrocenium salts. The redox potentials of the synthesized ferrocenes were determined by cyclic voltammetry, and it was observed that all new ferrocenium salts have stronger oxidizing properties than standard ferrocenium hexafluorophosphate. An initial application of selected derivatives in an oxidative bicyclization revealed that they mediate the transformation under considerably milder conditions than ferrocenium hexafluorophosphate. Quantum chem. calculations of the reduction potentials of the substituted ferrocenium ions were carried out by using a standard thermodn. cycle that involved the gas-phase energetics and solvation energies of the contributing species. A remarkable agreement between theory and experiment was found: the mean average deviation amounted to only 0.030 V and the maximum deviation to 0.1 V. This enabled the anal. of various phys. contributions to the computed reduction potentials of these ferrocene derivatives, thereby providing insight into their electronic structure and physicochem. properties.
This literature about this compound(1273-73-0)Electric Literature of C10BrFehas given us a lot of inspiration, and I hope that the research on this compound(Bromoferrocene) can be further advanced. Maybe we can get more compounds in a similar way.
