Solvent effects on the redox characteristics of different hydrazyls in nonaqueous media

Solvent Effect on the Redox Characteristics of Different Thiadiazoles in Nonaqueous Media

“…As can be seen in Table 1 DE 1/2 for all the investigated thiadiazoles (1a ±d, 2b ±d) decreased when the solvent changed from 1,2-dichloroethane to acetonitrile; i.e., the sum of the solvation energies increased which is in full agreement with that found in the literature [11]. This is in accordance with Gutmann×s donor model [15].…”

“…This behavior can be attributed to a solvent effect, as already reported by many workers [11,16,17].…”

“…The reference electrode was Ag/AgCl/Cl À (sat. AN) and the potential (E 1/2 ) values are referred to the redox potential of cobaltocenium/cobaltocene system [11]. …”

Electrochemical Study of Some Substituted Chromene Derivatives in Nonaqueous Media at Pt, Au and Glassy Carbon Electrodes

“…All the purified solvents were stored under argon in the dark. Purification of different solvents was carried out according to the literature [7,11,12].…”

“…The electrochemistry of heterocyclic compounds with nitrogen heteroatom has been extensively studied [1][2][3][4][5][6][7][8][9]. In spite of great importance and wide uses of the heterocyclic aromatic compounds with oxygen or sulphur atoms, it is rare to find an attempt to study their electrochemical redox characteristics.…”
