Parkanyi, Cyril; Vernin, Gaston; Zamkostian, Rose Marie; Metzger, Jacques published the artcile< Photolysis of bromothiazoles in hydrogen-donating solvents. A theoretical study and physical properties of bromothiazoles>, Product Details of C3HBrClNS, the main research area is photodebromination bromothiazole mechanism; NMR proton bromothiazole; UV bromothiazole fluorescence phosphorescence; mass spectra bromothiazole.
A PPP treatment and UV, fluorescence, phosphorescence, and 1H NMR indicate that the photodebromination of bromothiazoles (to give thiazole and isothiazole) in H-donating solvents involves C-Br bond homolysis in the first excited singlet state to give a thiazolyl radical which abstracts H. In the presence of amines the mechanism involves an electron transfer to form an exciplex in which the bromothiazole anion radical loses Br- to give the thiazolyl radical. The photodebromination reactivity order, 2-bromothiazole > 5-bromothiazole ≫ 4-bromothiazole, reflects the ground state C-Br bond strengths; this is supported by the mass spectra of the bromothiazoles.
