FIELD: chemistry.
SUBSTANCE: invention relates to a method for producing tricyclic organic diperoxides of general formula (I), where R1= lower alkyl; R2= lower alkyl; R3= branched or unbranched lower alkyl, substituted or unsubstituted phenyl; R4=H, lower alkyl, СН2СН=СН2; R5=H, by interaction of B,y’-triketones of general formula (II) with hydrogen peroxide in the presence of BF3⋅Et2O, HClO4, HBF4 or p-TsOH as a catalyst in acetonitrile or ethanol and the process is carried out mainly at a molar ratio of B,y’-triketone II : catalyst : hydrogen peroxide 1:(0.5-15):(2-5) at room temperature.
EFFECT: new method for the preparation of tricyclic organic diperoxides in high yield is developed, as well as an expansion of the range of tricyclic organic diperoxides of general formula I, which can be used as initiators of radical polymerization and in medicine as antiparasitic agents.
