Determination of rate constants for quenching singlet oxygen by chemiluminescence technique

Overall rate constants have been found for quenching¹O₂ generated under thermal decomposition of hydrotrioxides ROOOH, by several unsaturated species at 0°C. CH₃CH(OH)OOOHm (CH₃)₂C(OH)OOOH, CH₃C(OC₂H₅)₂OOOH and CH₃C(O) CH(OOOH) (CH₂)₂CH₃ were used as ROOOH; unsaturated compounds were 1,3-diphenylisobenzofurane, 2-methylfurane, 2,3,4,5-tetraphenylfurane, furfuroldiacetate, tetramethylethylene, adamantylideneadamantane, exo,-exo-2,3-dioxymethyl-7-adamantylidenenorbornane, exo,-exo-2,3-(2¹-oxatrimethylene)-7-adamantylidenenorbornane, 1,3-cyclohexadiene, (E,E)-8, 10-dodecadienol, cyclooctatetraene and isoprene.
