In 2019,Asian Journal of Organic Chemistry included an article by Paul, Dipankar; Borah, Apurba; Khatua, Snehadrinarayan; Nath Chatterjee, Paresh. Computed Properties of C7H9NO2S. The article was titled 《para-Toluenesulfonic Acid-Catalyzed, Ultrasound-Promoted, One-Pot, Three-Component Coupling of Aldehydes, -Dicarbonyls/Amides and Electron-Rich Arenes》. The information in the text is summarized as follows:
An ultrasound-promoted, metal-free method for the three-component coupling of aldehydes, β-dicarbonyls/amides and electron-rich arenes was reported. The versatility of the method was established by employing varieties of functionally diverse components for coupling. In lieu of expensive, toxic or specifically designed catalysts, the method presented employed com. available, inexpensive and non-toxic para-toluenesulfonic acid monohydrate (pTSA) as an efficient catalyst. An insight into the mechanistic pathway of the three-component coupling reaction was also provided by isolating the intermediate and subsequently converting it to the final product. The flexibility of choosing the components in the method described allowed one-pot access to a variety of relevant organic motifs. In the experiment, the researchers used many compounds, for example, 4-Methylbenzenesulfonamide(cas: 70-55-3Computed Properties of C7H9NO2S)
4-Methylbenzenesulfonamide(cas: 70-55-3) belongs to anime. In organic chemistry, amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (NH3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines).Computed Properties of C7H9NO2S
