摘要:

AbstractUsing PTC or cosolvent, both perfluoroalkyl bromides such as Br (CF2)2O(CF2)2SO2Na (1), Br(CF2)2OCF2CO2H (2), Cl(CF2)4Br (3), Cl(CF2Br (4),n‐C6F13Br (5),n‐C8F17Br (6), H(CF2)8Br (7), α, ω‐dibromides O(CF2CF2Br)2(8), Br(CF2)6Br (9) and Br(CF2)8Br (10) reacted readily with Na2S2O4in the presence of NaHCO3in aqueous solution to form the corresponding perfluoroalkane sulfinates NaO2S(CF2)2O(CF2)2SO2Na (11), NaO2S(CF2)2OCF2CO2Na (12), Cl(CF2)4SO2Na (13), Cl(CF2)2SO2Na (14),n‐C3F13SO2Na (15),n‐C8F17SO2Na (16), H(CF2)8SO2Na (17), α, ω‐disulfinates O(CF2CF2SO2Na)2(18), NaO2S(CF2)4SO2Na (19) and NaO2S(CF2)8SO2Na (20) in 66—97% yields. To this new and general reaction of perfluoroalkyl bromides, the name sulfinatodebromin
