The electrochemical behaviour of quinazoline in aqueous methanolic solutions has been studied in detail. In acid solutions two single-electron waves of equal height are obtained whereas in neutral solutions a single two-electron wave is observed. Quinazoline gets reduced to tetrahydroquinazoline in alkaline media and very interestingly gives "reverse cathodic peaks" during cyclic voltammetric experiments. The polarographic waves are diffusion-controlled and irreversible on the basis of the usual criteria. Based on the results obtained, reduction schemes are given for quinazoline in various buffered media. A comparison of the electrochemical behaviour, between quinazoline and 4-(2′-thienyl)quinazoline (4-TQ) has been attempted. © 1984 Springer-Verlag.
