The electrochemical reduction of 2-oxy-4,6-dimethylpyrimidine on platinum and rhodium electrodes

Abstract

1. The reduction of 2-oxy-4,6-dimethylpyrimidine in aqueous buffer solutions and on electrodes with low hydrogen-overvoltage (Pt and Rh) proceeds through an electrocatalytic mechanism leading to the formation of 2-oxo-4,6-dimethyl-1,3-diazacyclohexane. 2. The fact that neither the solution pH nor the nature of the metal had any effect on the reduction rate could be due to peculiarities in the adsorptional behavior of the 2-oxy-4,6-dimethylpyrimidine.
