Photochemical formation of thiirene and thioketene in 1,2,3-thiadiazoles with phenyl substituents studied by time-resolved spectroscopy

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 (a millisecond time scale thiirenes with phenyl substituents undergo an intermolecular reaction (dimerization of thiirene-thioketene complexes) leading to 1,3-dithiole derivatives.

Photochemical and Thermal Reactions of Heterocycles. Part 3. Photoisomerisation, Photofragmentation, and Photodimerisation of Mesoionic 1,3-Dithiol-4-one and -4-imine Derivatives

Photolysis of the mesoionic 2,5-diphenyl-1,3-dithiol-4-one (7) gave tetraphenyl-1,4-dithiin, tetraphenylthiophen, diphenylacetylene, and sulphur via the corresponding dimer (11) and 4,5-diphenyl-1,2-dithiol-3-one (12) which were isolable under appropriate conditions.Photolysis of the mesoionic N-benzoyl-2-phenyl-1,3-dithiol-4-imines (14) afforded the corresponding 1,2-dithiol-3-imines (15).The photochemical paths of the mesoionic dithiole systems are discussed in the light of the experimental results.
