The invention relates to a method for carrying out the in-situ decomposition of peroxides during the ozonolysis of optionally substituted alkenes in order to form the corresponding aldehydes or ketones. According to the method, the optionally substituted alkenes are reacted in water, a C1-C4 carboxylic ester, a C1-C4 carboxylic acid, a water/C1-C4 carboxylic acid mixture, a C1-C6 alcohol or in a water/C1-C6 alcohol mixture at a temperature ranging from -30 °C to +50 °C, in the presence of a heterogeneous inorganic catalyst selected from the group consisting of iridium, manganese, cobalt, silver, gold, palladium, platinum or ruthenium, which is applied to a supporting material selected from the group consisting of calcium carbonate, coal, titanium dioxide, magnesium oxide, zirconium oxide, silica or aluminum oxide or in the presence of a homogeneous inorganic catalyst selected from the group consisting of transition metal catalysts while simultaneously decomposing peroxides with ozone. Afterwards, the catalyst is separated out from the reaction mixture once the ozonolysis is complete thus obtaining corresponding aldehydes and ketones.
