FIELD: chemistry.
SUBSTANCE: invention relates to novel method of obtaining previously undescribed ketotetraoxanes of general formula I: 
where R=H, CH3 or NO2, by interaction of β,δ-triketones of general formula II: 
where R has upper mentioned values, with hydrogen peroxide in presence of phosphomolybdic acid (PMA) in medium of mixture of carbon tetrachloride with diethyl ether at room temperature and molar ratio β,δ-triketone II:PMA:hydrogen peroxide = 1:(0.3-0.5):(2.5-3.5). In the process mixture of carbon tetrachloride and diethyl ether (CCl4-Et2O) is applied at ratio (4-5):1 respectively. Obtained compounds can be of interest as initiators of radical polymer polymerisation, as well as in medicine and pharmaceutics as antiparasitic preparations.
EFFECT: method is technological, single-stage and safe.
