Reactivity of 3-hydroxy-3-methyl-2-butanone: Photolysis and reaction kinetics
25 26 Hydroxycarbonyl compounds are important secondary reaction products in the 27 oxidation of Volatile Organic Compounds (VOCs) in the atmosphere. The 28 atmospheric fate of these oxygenated VOCs is however poorly understood, 29 especially the relevance of the photolytic pathway. In this work, a combined 30 investigation of the photolysis and temperature-dependent OH radical reaction of 331 ...

متن کاملFlash photolysis of caged compounds
Photolabile ‘caged’ compounds are biologically inert precursors of active molecules, which when irradiated with a pulse of light free the active species at its site of action (see Fig. 1). Speed is the principal advantage offered by these probes; photochemical reactions can be very fast, with release of the active species often complete within a millisecond. The method can thus be used to study...
متن کاملHigh-spin intermediates of the photolysis of 2,4,6-triazido-3-chloro-5-fluoropyridine
In contrast to theoretical expectations, the photolysis of 2,4,6-triazido-3-chloro-5-fluoropyridine in argon at 5 K gives rise to EPR peaks of just two triplet mononitrenes, two quintet dinitrenes, and a septet trinitrene. EPR spectral simulations in combination with DFT calculations show that observable nitrenes can be assigned to triplet 2,4-diazido-3-chloro-5-fluoropyridyl-6-nitrene (D T = 1...
متن کاملXarboxymethylcysteine from the Photolysis
Photolysis of ethyl diazomalonyl trypsin and of ethyl diazomalonyl chymotrypsin, followed by hydrolysis, yields several products. One of the major products has now been identified as S-carboxymethylcysteine. Since neither trypsin nor chymotrypsin contains an -SH bond, the reaction must involve cleavage of a disulfide bond by the carbene generated on photolysis. The products so far identzed from...
