photochemical formation of thiirene and Thioketene in 1 2 3 thiadiazoles with phenyl substituents studied by time resolved spectroscopy
Photochemical and Photobiological Sciences, 2013Co-Authors: Gotard Burdzinski, Stephanie Delbaere, Michel Sliwa, Tomasz Pedzinski, Yunlong Zhang, Julien RehaultAbstract:Photochemistry of 4-phenyl-1,2,3-thiadiazole (PT) and 4,5-diphenyl-1,2,3-thiadiazole (DPT) in solution was studied at room temperature using UV-vis and IR transient absorption spectroscopies (λex = 266 nm). Ultrafast techniques show a very fast rise (<0.3 ps) of thiirene and Thioketene species, formed from 1,2,3-thiadiazoles in the singlet excited state. The remarkable unimolecular stability of thiirenes in solution is observed. On a millisecond time scale thiirenes with phenyl substituents undergo an intermolecular reaction (dimerization of thiirene–Thioketene complexes) leading to 1,3-dithiole derivatives.

Early events in the photochemistry of 1,2,3-thiadiazole studied by ultrafast time-resolved UV-vis and IR spectroscopies.
Journal of Physical Chemistry A, 2011Co-Authors: Gotard Burdzinski, Michel Sliwa, Yunlong Zhang, Stephanie DelbaereAbstract:Photochemistry of 4-methyl-5-carboethoxy-1,2,3-thiadiazole (MCT) in solution was studied at room temperature using UV–vis and IR transient absorption spectroscopies (λex = 266 nm). Three deactivation pathways are discussed: thiirene formation, Thioketene generation, and the internal conversion by repopulating MCT in the ground state. Ultrafast techniques show a very fast rise (
