Electrochemical Study of Flavonoids in Acetonitrile: Structure-Activity Relationships

Relations between structure, antioxidant capacity and formal redox potentials (E°’) of six flavonoids dissolved in acetonitrile were studied by cyclic voltammetry and square wave voltammetry using a glassy carbon electrode. This work shows correlation between the electrochemical parameter E°’ and the number of hydroxyl groups present in the B ring of flavonoids. Besides, it has been observed th...

Spectrophotometric and Electrochemical Study of the Complexation of Iodine with 1,10-Diaza-18-Crown-6 in Acetonitrile Solution

The complexation reaction between iodine and 1,10-Diaza-18-Crown-6 (DA18C6) has been studied in acetonitrile by spectrophotometric, biamperometric and conductometric techniques. The results are indicative of the formation of [(CH3CH)nI+.I¯3] from iodine and acetonitrile, and the formation of DA18C6 I+. I¯ from DA18C6 and [(CH...

Electrogenerated chemiluminescence. 30. Electrochemical oxidation of oxalate ion in the presence of luminescers in acetonitrile solutions

The electrochemical oxidation of oxalate at a platinum electrode in acetonitrile solutions as studied by cyclic and rotating-ring disk voltammetry and controlled potential coulometry shows an irreversible two-electron oxidation at ca. 0.3 V vs. SCE to CO2 with no intermediates detectable by these techniques. The oxidation of oxalate in the presence of several fluorescers (such as rubrene, 9, IO...

Effect of Sodium Ions on the Electrochemical Reduction of Diethyl Fumarate in Dimethylsulfoxide and Acetonitrile

Control of the electrochemical reduction of horminone by pH imposition in acetonitrile

An electrochemical study using transient techniques of a quinone-type natural product, horminone, has been performed in acetonitrile in the presence of two buffer solutions of pH = 17.2 and pH = 15.5. Using linear sweep voltammetry, it was found that at both pH values the reduction mechanism of horminone involves a monoelectronic charge-transfer step, followed by a protonation step and homogene...
