New discoveries in chemical research and development in 2021. Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. In a patent, 5908-62-3, name is 1,1-Dioxo-isothiazolidine, introducing its new discovery. Recommanded Product: 1,1-Dioxo-isothiazolidine
N-(3-Pyridinyl)-substituted secondary and tertiary sulfonamides have been synthesized in good to excellent yields by the reaction of 3-bromopyridine with primary and secondary alkyl and aryl sulfonamides (MeSO2NH2, MeSO2NHMe, TolSO2NH2, TolSO2NHMe, 1,3-propanesultam, and 1,4-butanesultam), catalyzed by CuI (20 mol %) and 1,3-di(pyridin-2-yl)propane-1,3-dione (20 mol %) with K2CO3 (200 mol %) in DMF (0.17 M for ArBr) at 110-120 C over 36-40 h. 2-Bromopyridine, 4-bromopyridine, and a wide variety of substituted phenyl bromides can also be successfully coupled with sulfonamides under these reaction conditions.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, Recommanded Product: 1,1-Dioxo-isothiazolidine, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about Recommanded Product: 1,1-Dioxo-isothiazolidine
