Abstract
Electrochemical oxidation of ten derivatives of 6H-pyrimido[2,1-a]isoindole in anhydrous acetonitrile was studied; the attention was focused on the influence of the substituent structure and the position on the electrochemical behaviour of the studied c mpounds. The study was performed by DC voltammetry, potentiostatic coulometry, and cyclic voltammetry.
All derivatives gave a single anodic wave with the half-wave potential in the range 1.34 1.62V. The numbers of exchanged electrons were in the range 097 1.35.
The cyclic voltammetry at scan rates lower than 1 Vs-1 showed only one peak, which decayed at the second scan.
