Photochemical rearrangements in heterocyclic series. III. Arythiazoles and arylisothiazoles isomers. Experimental results and theoretical study was written by Vernin, G.;Riou, C.;Dou, H. J. M.;Bouscasse, L.;Metzger, J.;Loridan, G.. And the article was included in Bulletin de la Societe Chimique de France in 1973.COA of Formula: C9H7NS This article mentions the following:
In the presence of I2 the photoisomerization of 3 phenylthiazoles and 3 phenylisothiazoles was selective. Five possible mechanisms from published data were examined; those best fitting the results were a valence isomerization mechanism with or without preliminary opening of weaker bonds in the 1st excited state and a mechanism involving torsion of bonds adjacent to S. In the experiment, the researchers used many compounds, for example, 5-Phenylthiazole (cas: 1826-13-7COA of Formula: C9H7NS).
5-Phenylthiazole (cas: 1826-13-7) belongs to thiazole derivatives. Thiazoles are a class of five-membered rings containing nitrogen and sulfur with excellent antitumor, antiviral and antibiotic activities. Thiazole sulfonation occurs only under forcing conditions: the action of oleum at 250 °C for 3 hours in the presence of mercury(II) sulfate leads to 65% formation of 5-thiazole sulfonic acid.COA of Formula: C9H7NS
