A kinetic study of the chemiluminescent (CL) reaction mechanism of lophine-derived hydroperoxides and silylperoxides induced by a base and fluoride, respectively, provided evidence for the formation of a 1,2-dioxetane as a high-energy intermediate (HEI) o

A linear correlation existed between the absorption energy of activators (Eo-o's) and the sensitized chemiluminescence (CL) yields (φSCL's) for the CL reaction of lophine peroxides (2a and 2b), whereas a linear correlation did not exist between their oxidation potentials (Eox's) and φSCL's. Based on the finding, an energy transfer mechanism is likely rather than an electron transfer mechanism like the CIEEL mechanism.

The present invention provides a heat-generating agent or singlet oxygen-generating agent effective as a new cancer treatment agent which, unlike an anticancer agent based on an alkylating agent such as MMC, uses the action of heat and/or singlet oxygen to kill cancer cells and reduce the burden on patients. A heat- and/or singlet oxygen-generating agent or a cancer treatment agent, comprising an organic peroxide such as the peroxide of an imidazole derivative or a chemiluminescent compound such as a dioxetane compound.
Location effect of an OH group on the chemiluminescence efficiency of 4-hydroperoxy-2-(o-, m-, or p-hydroxyphenyl)-4,5-diphenyl-4H-isoimidazoles

In studying the location effect of an OH group on the chemiluminescence efficiency of 4-hydroperoxy-2-(o-, m-, or p-hydroxyphenyl)-4,5-diphenyl-4H- isoimidazoles 4, we found that the efficiency of 4a with o-OH was 0.28 times that of lophine peroxide on initiation with KOH/MeOH. When the trigger base was changed to TBAF/THF, efficiency was 530-fold in dry DMF. The efficiency of 4b with m-OH or 4c with p-OH showed no such dramatic change.
