✦ Synopsis

The electrochemical behaviour of 4(2'-thienyl)quinazoline (6TQ) was studied in acid solutions of varying ionic strengths using polarography, cyclic voltammetry and controlled-potential electrolysis. 4-TQ is reduced in two single electron steps to give the dihydro-4-TQ product. The two polarographic waves were found to be diffusion-controlled, the first wave being reversible and the second wave irreversible. On the bask of the results obtained, a mechanism is suggested for 4-TQ reduction in which a dimerization reaction goes in parallel with the electron-transfer step.

The pohuographic reduction of 2,4,6trinitro diphenylamine was found to give three waves of nearly equal height in all pH regions in buffered solutions and also in unbuffered methanol-water mixtures. The waves were shown to be diffusion-controlled and irreversible on the basis of the usual criteria.
