In the presence of sodium dithionite, perfluoroalkyl bromides reacted with olefins readily in aqueous iso-propanol solution under mild conditions, giving the corresponding addition–sulfination products, RFCH2CH(R)SO2Na, in good yields. A radical mechanism was proposed for this reaction.
在连二亚硫酸钠存在下,全氟烷基溴化物在温和的条件下在异丙醇水溶液中容易与烯烃反应,从而以高收率得到相应的加成硫化产物R F CH 2 CH(R)SO 2 Na。提出了用于该反应的根本机理。
