Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 58446-52-9, Name is 1-Phenylicosane-1,3-dione, molecular formula is , belongs to isothiazole compound. In a document, author is ADAMS, GW, SDS of cas: 58446-52-9.
NEGATIVE-ION FRAGMENTATIONS OF DEPROTONATED HETEROCYCLES – THE ISOTHIAZOLE, THIAZOLE, ISOXAZOLE, AND OXAZOLE RING-SYSTEMS
The major collision-induced dissociations of deprotonated isothiazole occur from the 5-anion, while deprotonated thiazole fragments almost equally through the 2- and 5-anions. Both 5-anions fragment by a simple retro cleavage yielding HC2S- and HCN. The 5-anion of isothiazole and the 2-anion of thiazole also rearrange to the common intermediate -SCH = CHCN which decomposes by losses of H-2, HCN and H2S, There is no evidence for direct interconversion of isothiazole and thiazole anions. The spectra of deprotonated methylisothiazoles and methylthiazoles are complex, but the major fragmentations are of ring deprotonated ions and are generally analogous to the parent systems. The fragmentation behaviour of deprotonated isoxazole and oxazole is analogous to that of the isothiazole and thiazole systems.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 58446-52-9, in my other articles.
