Chemiluminescence of Ru(bpy)3Cl2 complex during the thermolysis of diphenyldiazomethane in the presence of oxygen

Dioxiranes: from oxidative transformations to chemiluminescence

“…Dioxirane was also proposed as an intermediate to explain the CL of peroxyoxalate. 99 Later 12 we have observed non-sensitised CL in the Ph 2 CCl 2 ± H 2 O 2 ± NaOH system, similar to the Steinfatt systems. The maximum of the luminescence intensity was concentrated in the range 400 ± 450 nm, pointing to the possible formation of triplet phenyl benzoate, the product of isomerisation of diphenyldioxirane.…”

“…6 Detection of the EPR signal of the radical cation 41 + . , formed in the reaction of pyrene with the dioxirane 1b by reaction (12), is an additional argument pointing to the CIEEL mechanism in the chemiluminescence reactions of dioxiranes. 272 The reaction of the dioxirane 1a with PAH is also accompanied by CL.…”

“…A dioxirane intermediate has been postulated to interpret the mechanism of bioluminescence of bacteria. 101 Recently, we suggested that chemiluminescence in the Ph 2 CCl 2 ± NaOH ± H 2 O 2 system, which is similar to the Steinfatt systems, is also associated with a dioxirane 12 (studies…”

“…Thus ruthenium tris(bipyridine) complex Ru(bipy) 2 3 and some polyaromatic hydrocarbons, which act as activators of the CL arising by the chemically initiated electron-exchange luminescence (CIEEL) mechanism, catalyse isomerisation of dioxirane. 6,10,12,15,16,123 Apparently, the Silipor surface also functions as a catalyst. 11,16 e. Catalysed (induced) decomposition of dimethyldioxirane by impurities Some impurities have an exceptionally significant influence on the stability and the decomposition mechanism of the dioxirane 1a.…”

Chemiluminescence occurring upon decomposition of dimethyldioxirane adsorbed from the gas phase onto a silipor surface in the presence of tris(bipyridine)ruthenium(II) and 9,10-diphenylanthracene

“…5 The same phenomenon was observed upon interaction of dioxiranes with tris(bipyridine)ruthenium(II) [Ru(bipy) 3 ] 6 and some aromatic hydrocarbons. 2,7 In addition, dioxirane as intermediate has been postulated as a source of chemiluminescence in a number of chemical 8,9 and biochemical 10 systems.…”
