Chemistry graduates have much scope to use their knowledge in a range of research sectors, including roles within chemical engineering, chemical and related industries, healthcare and more. , Recommanded Product: 2-Chloro-10H-phenothiazine, 92-39-7, Name is 2-Chloro-10H-phenothiazine, molecular formula is C12H8ClNS, belongs to thiazines compound. In a document, author is Shen, Shusu, introduce the new discover.
Synthesis of 6-Alkylidene-5,6-dihydro-4H-1,3-thiazine Derivatives via the Cyclization of N-3-Bromo-3-alkenylthioamides
By the treatment of N-3-bromo-3-alkenylthioamides with sodium hydroxide in DMF-H2O in the presence of tetra-butylammonium bromide, series of 6-alkylidene-5,6-dihydro-4H-1,3-thiazine derivatives were prepared in moderate to good yields. The cyclization is supposed to proceed via both the intramolecular vinylic nucleophilic substitution and the elimination-addition mechanisms (formation of acetylenic intermediates) in a competitive manner.
Recommanded Product: 2-Chloro-10H-phenothiazine, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 92-39-7 is helpful to your research.
