Secondary propene ozonide and isobutene ozonide were formed in the gas
-phase ozonolysis of ethene with added acetaldehyde and acetone, respe
ctively. Combined with the formation of hydroperoxymethyl formate and
methoxymethyl hydroperoxide in the ethene-ozone reaction system in the
presence of HCOOH and CH3OH, respectively, formation of the secondary
ozonides reveals a close similarity between the gas-phase and the liq
uid-phase ozonolysis of alkenes. Copyright (C) 1996 Elsevier Science L
