Regeneration of the Ru(bipy)3Cl2 excitation under chemiluminescence activation in the reaction of diphenylmethane autooxidation in an alkaline medium

The effect of the Ru(bipy)3Cl2 [RuII] complex on chemiluminescence in the autooxidation of diphenylmethane in the presence of BuIOK was studied. The luminescence increases due to the participation of an activator in the redox processes. The excitation of the RII complex occurs in the stage of oxidation by the superoxide anion of the RuI complex formed by the one-electron reduction of the initial RuII by anions.

Chemiluminescence testing of solutions to detect organometallic peroxides during oxidation of organometallic compounds by oxygen

Conclusions1.The possibility of detecting organometallic peroxides without decreasing the temperature and hydrolysis of the reaction solution during oxidation of organometallic compounds with oxygen based on the kinetic maxima of the intensity of chemiluminescence was demonstrated.2.The formation of organometallic peroxides was detected during oxidation of organic derivatives of uranium and lanthanides with oxygen.3.The stage of formation of an organometallic peroxide during oxidation of organometallic compounds with oxygen takes place more rapidly than the reactions of its subsequent consumption.

Chemiluminescence accompanying the thermal decomposition of diethoxy(tert-butyl hydroperoxidato) aluminum

ConclusionsThe thermolysis of diethoxy(tert-butyl peroxide) aluminum takes place with the formation of products in electronically excited states without the participation of free radicals. One of the emitters of luminescence is acetaldehyde.

Effect of oxygen on the chemiluminescence during the oxidation of ethylaluminum diethoxide by xenon difluoride in solution

Conclusions1.The effect of oxygen on the chemiluminescent reaction of alkyl organoaluminum compounds with xenon difluoride was determined. The emission becomes stronger or weaker depending on the concentration of oxygen in the solution.2.In addition to the main source of emission (reactions not containing O2 radicals), there is an additional source due to the transformation of the alkyl radicals (reaction intermediates) into peroxyl radicals, which disproportionate with the emission of light.

Effect of the nature of the organoaluminum compound on the direction of the reaction with xenon difluoride

In the authors previous work, they reported the chemiluminescence of organoaluminum compounds (OAC) upon oxidation by XeF/sub 2/ in solution. In the present work, gas-liquid chromatography, elemental and gas volumetric analysis, F- and Cl-electrode-selective potentiometry, and chemiluminescence were used to determine that the attack by XeF/sub 2/ in the reaction of XeF/sub 2/ with OAC such as Et/sub 3/Al (I), (EtO)/sub 2/AlEt (II), Et/sub 2/AlCl (III), and (t-Bu)/sub 2/AIH (IV) proceeds only at the Al-R bond. The C-H bonds of the alkyl groups of OAC do not participate in this reaction, which indicates the possibility of using the reaction of OAC and XeF/sub 2/ for the synthesis of OAC with an Al-F bond.

Bright chemiluminescence upon the oxidation of organoaluminum compounds by xenon difluoride

Chemiluminescence was found in the reaction of XeF/sub 2/ with (C/sub 2/H/sub 5/)/sub 3/A1 (TEA), (i-C/sub 4/H/sub 9/)/sub 3/ X A1, (i-C/sub 4/H/sub 9/)/sub 2/A1H, and (C/sub 2/H/sub 5/)A1C1/sub 2/ in CH/sub 2/C1/sub 2/. The product composition indicates a redox reaction of XeF/sub 2/ with the A1-C bond. The kinetic curves for the chemiluminescence intensity which feature brightness maxima indicate luminescence excitation in reactions of unstable intermediates. Organoxenon compounds have been proposed for these intermediates.
