Synthesis and electrochemical properties of mono- and (�)-1,2-dialkylferrocenes and alkylferrocenium hexafluorophosphates in aqueous and micellar media

Cyclometalated N,N-dimethylbenzylamine ruthenium(II) complexes [Ru(C6HR1R2R3-o-CH2NMe2)(bpy)(RCN)2]PF6 for bioapplications: synthesis, characterization, crystal structures, redox properties, and reactivity toward PQQ-dependent glucose dehydrogenase

“…This is presumably due to an increase in the bulkiness of 3h on addition of an extra substituent. Similar effect has been reported for mono alkyl substituted ferrocenesan increase in the length of the alkyl radical results in a gradual anodic shift of redox potentials [29]. The same effect is obviously responsible for a higher redox potential of pivalonitrile complex 4a (535 mV) compared with its acetonitrile analog 2a (498 mV).…”

Dye regeneration and charge recombination in dye-sensitized solar cells with ferrocene derivatives as redox mediators

“…Electrochemical studies have previously been conducted on many of the selected ferrocene derivatives. 56,57,60,61 Nevertheless, to facilitate comparisons cyclic voltammograms were measured in the solvents used for the DSC electrolytes, acetonitrile and benzonitrile. The electrochemical measurements show that each ferrocene derivative undergoes a reversible one-electron redox process in acetonitrile (Fig.…”

Heat Capacities and Thermodynamic Functions of Propanoylferrocene and Propylferrocene

“…Propanoylferrocene (POF) (Figure ) was prepared by acylation of ferrocene with propionyl chloride, C 2 H 5 COCl, in a dry solution of methylene chloride, CH 2 Cl 2 . The reaction proceeded in the presence of aluminum chloride, AlCl 3 , as a catalyst . The reagents were taken in equimolar quantities that allowed us to minimize the impurities of ferrocene and 1,1′-dipropionyl-ferrocene in the final products.…”

“…The reaction proceeded in the presence of aluminum chloride, AlCl 3 , as a catalyst. 10 The reagents were taken in equimolar quantities that allowed us to minimize the impurities of ferrocene and 1,1′-dipropionyl-ferrocene in the final products. Propanoylferrocene was isolated from the reaction mixture by the column chromatography method (CCM) on silica gel.…”

“…Propylferrocene (PF) (Figure 1) was synthesized by the Clemmensen reaction of reducing propanoylferrocene with amalgam (Zn/Hg) in the presence of hydrochloric acid, HCl. 10 Propylferrocene was extracted from the reaction mixture by diethyl ether. The raw product underwent column chromatography on silica gel, and then PF was eluated with petroleum ether.…”
