The semivolatile ketoaldehydes 3,3-dimethyl-gamma-methylene-2-(3-oxobutyl)-cyclobutanebutanal and 3,3-dimethyl-gamma-oxo-2-(3-oxobutyl)-cyclobutanebutanal and formaldehyde have been identified as the main products of the reaction of beta-caryophyllene with ozone in the gas phase. In minor amounts 9-methylene-4,12,12-trimethyl-5-oxabicyclo[,5)]dodecane was also formed. Nature and yields of these carbonyl products are discussed in terms of oxidation mechanisms involving the gas phase reaction with ozone and OH radicals.
