UV (ArF and N2) laser photolysis and IR laser photosensitized (SF6) decomposition of gaseous secondary butene-2-ozonide (SBOZ) are shown to follow different reaction courses. ArF laser (193 nm) photolysis of SBOZ affords CO2, CH3OH, CH3CHO, CH4, HCOOH, CH2=C=O and C1-C4 hydrocarbons, while N2 laser (337 nm) photolysis of SBOZ is a much slower process than SBOZ oligomerization occurring on the reactor walls. The multiple of the ArF laser induced photolytic products is in line with a complex reaction scheme involving initial O-O and 2,3 C-O bond splits of 1,2,4-trioxolane ring. Continuous-wave CO2 laser photosensitized SBOZ decomposition affords CH3CHO and CH3COOH together with 1-hydroxylethyl acetate and 1-methoxyethyl formate, the products of rearrangement observed earlier in a pulsed CO2 laser SF6 photosensitized decomposition reported by us in a previous paper.

IR laser photosensitized (SF6) decomposition of 3,5-dimethyl-1,2,4-trioxolane (DMTO) in the gas phase yields acetic acid, acetaldehyde, 1-hydroxyethyl acetate, 1-methoxyethyl formate and high molecular mass solid products. The formation of esters provides evidence for the 1,4-H and 1,4-Me shift taking place after the initial O-O bond split in DMTO, confirming a previously postulated intermediate for the decomposition of secondary ozonides. The products reveal that the homogeneous decomposition of DMTO is more complex than previously postulated for the decomposition in the liquid- and gas-phase.
