[CoH1(salen)(DMF)2]+ X" salts [X = PF6, C104; salen = bis(salicyliden)ethylendiiminato; DMF = dimethylformamide] have been synthesized by electrochemical and chemical (air) oxidation of Co"(salen). Their monomeric structure with two DMF molecules in the axial positions in both the solid state and DMF solution is shown by X-ray crystal structure analysis, thermal analysis, mass spectroscopy, and 'H and l3C NMR spectroscopy. The electrochemical reduction of the [Coni(salen)(DMF)2]+ cation is investigated by cyclic voltammetry and com pared to the oxidation of the neutral CoH(salen). The redox reaction connecting the cobalt(II) and the cobalt(III) species appears to be a quasi-reversible electron transfer. These properties make the [Co1 1 (salen)(DMF)2]+ X-salts starting materials for the analysis of the interaction of basic substrates with cobalt(III) species in the context of the biomimetic oxygenation reactions catalyzed by such complexes.

“…In order to determine the homogenous kinetic constant k corresponding to the chemical addition of electrogenerated benzoquinones 2a-d onto L-cysteine 3a=, digital simulations of the hydroquinones 1a-d CVs in the presence of L-cysteine 3a= were performed using DigiSim software [82,83] and compared to experimental CVs as shown in Figure 5a for hydroquinone 1c. To obtain more accurate values of the different kinetic constants k, the evolutions of the I p /I p 0 ratios versus the CVs scan rate were fitted to the experimental data, as shown in Figure 5b for hydroquinone 1c.…”

We present herein a review of our work on the on-line electrochemical generation of mass tags toward cysteine residues in peptides and proteins. Taking advantage of the inherent electrochemical nature of electrospray generated from a microfabricated microspray emitter, selective probes for cysteine were developed and tested for on-line nonquantitative mass tagging of peptides and proteins. The nonquantitative aspect of the covalent tagging thus allows direct counting of free cysteines in the mass spectrum of a biomolecule through additional adduct peaks. Several substituted hydroquinones were investigated in terms of electrochemical properties, and their usefulness for on-line mass tagging during microspray experiments were assessed with L-cysteine, peptides, and intact proteins. Complementarily, numerical simulations were performed to properly understand the respective roles of mass transport, kinetics of electrochemical-chemical reactions, and design of the microspray emitter in the mass tagging overall efficiency. Finally, the on-line electrochemical tagging of cysteine residues was applied to the analysis of tryptic peptides of purified model proteins for protein identification through peptide mass fingerprinting.
