Key words: ozone, ozonation of organic substances, supercritical carbon dioxide (SC-CO2), dicyclopentadiene
The new original procedure for preparative reactions of ozone with organic substrates in supercritical (SC) fluids as solvents is proposed. Reactions of ozone with o-isopropenylaniline and dicyclopentadiene as model substrates are investigated, and their products are identified using GC-MS, IR- and NMR-spectroscopies. It is demonstrated that in the case of reaction of ozone with o-isopropenylaniline SC-CO2 not only plays the role of efficient solvent for both ozone and organic substrate, but also stabilizes ozone (prevents its decomposition) and participates in the process as a co-reactant.
