Abstract
Oxidation of 5-hydroxy-6-methyluracil with molecular oxygen in the presence of copper(II) chloride involves formation of a 2 : 1 complex with copper(II). The rates of consumption of initial 5-hydroxy-6-methyluracil and oxygen were determined in the temperature range from 40 to 80°C. A probable reaction mechanism implies fixation and activation of molecular oxygen on the copper(II) complex with 5-hydroxy-6-methyluracil with formation of active oxygen species that are responsible for hydroxylation of the double C5=C6 bond in the uracil molecule.
