Career opportunities within science and technology are seeing unprecedented growth across the world, and those who study chemistry or another natural science at university now have increasingly better career prospects. , Quality Control of Methanesulfonic anhydride, 7143-01-3, Name is Methanesulfonic anhydride, molecular formula is C2H6O5S2, belongs to thiazines compound. In a document, author is Bognar, Balazs, introduce the new discover.
Reaction of -Bromo-,-unsaturated Pyrroline Nitroxide Aldehydes and Nitriles with Aromatic N,S-Binucleophiles
Reactions of -bromo-,-unsaturated pyrroline nitroxide aldehyde (1) or nitrile (4) or their diamagnetic forms (5, 6) with 2-aminothiophenol or 2-mercaptobenzimidazole were evaluated. The reaction could be reproduced more easily with the application of O-acetyl derivatives of nitroxides to generate 2-substituted-benzothiazole, pyrrolo[3,4-b]benzo[1,5]tiazepine scaffolds with 2-aminothiophenol and benzimidazo[2,1-b]pyrrolo[3,4-e]-[1,3]thiazine scaffold with 2-mercaptobenzimidazole.
