| Abstract | A novel technique is presented that allows detection of free radicals from ozone-olefin reactions for the first time. Olefins are ozonated at -7Q°C, the unreacted ozone removed, the spin trap added, and the solution warmed. The radicals spin trapped indicate that trioxygenated intermediates are produced that decompose to radicals on warming. Ozonation of cyclic acetals by this procedure yields acyl hydrotrioxides that decompose on warming to produce hydroperoxyl radi cals , H00’. Alkoxyl radicals are spin trapped when mainstream cigarette smoke is bubbled through PBN solutions while acyloxyl radicals are trapped from sidestream smoke. Stable radicals detected in tar are found by fractionation to be similar to the animal pigment, melanin. |
