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

The thermal reaction of chiral 2-phenyl-4-(p-X-phenyl)-5-(p-Y-phenyl)-4-tert-butyldimethylsilylperoxy-4H-isoimidazoles (5b: X = CF3, Y = OMe; 5c: X = CF3, Y = F) was carried out in DMSO. The chiral 2-phenyl-5-(p-X-phenyl)-5-(p-Y-phen

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.
