(フェニルスルホニル)ニトロメタン 化学特性,用途語,生産方法
合成
The Preparative Method of Phenylsulfonylnitromethane: Nitromethane, Sodium Benzenesulfonate, and Iodine have been added sequentially to a cold (0-5 °C) DMF solution of Sodium Methoxide. The reagent can be converted to NaO2N=CHSO2Ph (1) and LiO2N=CHSO2Ph (2) using NaOMe and LiOMe, respectively.
純化方法
Recrystallise the sulfone from CHCl3, or 95% EtOH, then sublime it at 100-120o/0.1 Torr and recrystallise again. It is an acidic analogue of nitromethane used for the general synthesis of aliphatic acids and nitriles and in cycloaddition reactions with olefins to form heterocycles. [Wade et al.
