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[double bond, length as m-dash]C[double bond, length as m-dash]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.
