Extended knowledge of 640-61-9

The chemical industry reduces the impact on the environment during synthesis N,4-Dimethylbenzenesulfonamide. I believe this compound will play a more active role in future production and life.

Electric Literature of 640-61-9, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 640-61-9, name is N,4-Dimethylbenzenesulfonamide, This compound has unique chemical properties. The synthetic route is as follows.

General procedure: To a resealable Schlenk tube was added Fe3O4SiO2-P-AuOTf (66 mg, 0.025 mmol). The reaction tubewas evacuated and back-filled with argon and this evacuation/back-fillprocedure was repeated one additional time. Alkynylcyclopropane(0.5 mmol), sulfonamide (0.6 mmol) and DCE (5 mL) were then addedunder a stream of argon. The reaction tube was quickly sealed and thecontents were stirred while heating in an oil bath at 100 C for 24 h. After thereaction mixture was cooled to room temperature, the supported goldcatalyst was magnetically separated and the reaction mixture wasconcentrated under vacuum and then purified by flash chromatography(petroleum ether/ethyl acetate = 7:1) to afford the corresponding product.The recovered gold catalyst was washed with DCE (2 2 mL), air-dried andused directly for the next run.

The chemical industry reduces the impact on the environment during synthesis N,4-Dimethylbenzenesulfonamide. I believe this compound will play a more active role in future production and life.
