Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 6192-52-5, Name is 4-Methylbenzenesulfonic acid hydrate, molecular formula is C7H10O4S, belongs to thiazines compound, is a common compound. In a patnet, author is Guan, Zong, once mentioned the new application about 6192-52-5, Recommanded Product: 4-Methylbenzenesulfonic acid hydrate.
Organic Synthesis with N-Heterocyclic Carbenes of Indazole: Synthesis of Benzo(thio)imidates, Benzo[d][1,3]thiazines and Quinazoline-4-thiones
The N-heterocyclic carbenes of indazole, generated by deprotonation of indazolium salts, proved to be versatile starting materials for organic synthesis. They undergo ring-opening reactions to generate ketenimines which readily add thiols thus affording what are, to the best of our knowledge, the first examples of 2-anilinobenzothioimidates. Water converts the ring-opened intermediates into functionalized 2-anilinobenzamides which can be thionated with Lawesson’s reagent and subsequently cyclized with formaldehyde and propionaldehyde, respectively, to give benzo[d][1,3]thiazines and quinazoline-4-thiones. The outcome of the cyclization depends upon the thiobenzamide substitution pattern.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 6192-52-5. The above is the message from the blog manager. Recommanded Product: 4-Methylbenzenesulfonic acid hydrate.
