Redox data of ferrocenylcarboxylic acids in dichloromethane and acetonitrile.

Pieter J Swarts1, Jeanet Conradie1.   

Abstract

Redox data obtained from cyclic voltammetry experiments of the FeII/III oxidation of six ferrocenyl carboxylic acids is presented in this data in brief article. Data is obtained from the cyclic voltammograms at scan rates of two orders of magnitude (0.05 - 5.00 Vs-1) using (i) acetonitrile as solvent and tetrabutylammonium hexafluorophosphate as supporting electrolyte and (ii) dichloromethane as solvent and tetrabutylammonium tetrakispentafluorophenylborate, as the electrolyte. Data is reported versus the FeII/III redox couple of ferrocene. For more insight in the reported data, see the related research article "Solvent and substituent effect on Electrochemistry of ferrocenylcarboxylic acids", published in Journal of Electroanalytical Chemistry [1].

Specifications Table Value of the Data This data provides detailed electrochemical data for six ferrocenyl carboxylic acids in both DCM and ACN for scan rates over two orders of magnitude (0.05 – 5.0 Vs−1). This data illustrates the influence of the solvent used in cyclic voltammetry experiments, on the formal redox potential of Fe of the ferrocenyl group for ferrocenylcarboxylic acids. This data illustrates the influence of the solvent on the peak current-voltage separations, ΔEp, of the Fe oxidation peak of ferrocenyl carboxylic acids. This data illustrates the electronic influence of electron-withdrawing carbonyl group on the iron's oxidation potential, depending on how close the carbonyl group is to the iron. Accurate redox potential data of these ferrocenyl (Fc) carboxylic acids are important, since they are used as ligands in organometallic complexes.

Data

This article presents redox data of six ferrocene-containing carboxylic acids, 1 – 6, reported versus the redox couple ferrocene (Fc) at 0, using decamethylferrocene (DmFc) as internal standard [2], see Figure 1 for the series of complexes of this data study. Cyclic voltammograms obtained in dichloromethane (DCM) and acetonitrile (ACN) for compound 1 – 6, with DmFc as internal standard, are shown in Figure 2–Figure 9. The cyclic voltammograms of DmFc and ferrocene in DCM and ACN are shown in Fig. 10, Fig. 11. Electrochemical data obtained from the cyclic voltammograms at scan rates 0.05 Vs−1 – 5.00 Vs−1 are tabulated in Table 1–Table 12 (0.10 Vs−1data from reference [1]). Presented data is related to the research article “Solvent and substituent effect on Electrochemistry of ferrocenylcarboxylic acids”, published in Journal of Electroanalytical Chemistry [1]. The electronic influence of the different carboxylic acids substituents on the redox potential of the ferrocenylgroup they are attached to, is illustrated in Figure 2 and Figure 3. The electronic influence of the electron-withdrawing carbonyl group on the iron's oxidation potential, depends on how close the carbonyl group is to the iron. Redox data of ferrocene-containing compounds are important for application in asymmetric catalysis [3], [4], [5], [6], energy transfer processes [7], biological applications [8,9], as additives in highburning rate composite rocket propellants [10] and non-linear optics [6].

Experimental Design, Materials, and Methods

Electrochemical studies through cyclic voltammetry (CV) experiments were performed in an M Bruan Lab Master SP glove box under a high purity argon atmosphere (H2O and O2< 10 ppm), utilising a Princeton Applied Research PARSTAT 2273 potentiostat running Powersuite software (Version 2.58). The cyclic voltammetry experimental setup consists of a cell with three electrodes, namely (i) a glassy carbon electrode as working electrode, (ii) a platinum wire auxiliary and (ii) a platinum wire as pseudo reference electrode. The glassy carbon working electrode was polished and prepared before every experiment on a Buhler polishing mat first with 1-micron and then with ¼-micron diamond paste, rinsed with H2O, acetone and DCM, and dried before each experiment. The electrochemical analysis is performed in dichloromethane (DCM, anhydrous, ≥ 99.8%, containing 40-150 ppm amylene as a stabilizer) and in acetonitrile (ACN, anhydrous, 99.8%) as solvents, at RT. Solutions were made in 0.001 dm3 spectrochemical grade anhydrous DCM or ACN containing ca. 5 × 10−4 M of analyte, 5 × 10−4 mol dm−3 of internal reference (decamethylferrocene, DmFc) and 0.1 mol dm−3 of supporting electrolyte tetrabutylammonium tetrakispentafluorophenylborate, [N(Bu)4][B(C6F5)4] in DCM, or tetrabutylammonium hexafluorophosphate, TBAPF6, [N(Bu)4][PF6] in ACN. Experimental potential data was measured vs. the redox couple of decamethylferrocene DmFc as internal standard [2] and reported vs. the redox couple of ferrocene, Fc, as suggested by IUPAC [11]. E°`(DmFc) = -0.610 V vs. Fc/Fc+ at 0 V in DCM/[N(Bu)4][B(C6F5)4] and -0.520 vs. Fc/Fc+ at 0 V in ACN/[N(Bu)4][PF6]. Scan rates were between 0.05 and 5.00 Vs−1.
