The reaction of sodium perfluoroalkanesufinates with coumarin
摘要:
The reaction of sodium perfluoroalkanesufinates with coumarin in the presence of Mn(OAc)(3). 2H(2)O was studied. Sodium perfluoroalkanesufinates, RFSO2Na [R-F=F(CF2)(6), 2a; F(CF2)(7), 2b; F(CF2)(8), 2c; Cl(CF2)(4), 2d; Cl(CF2)(6), 2e],reacted readily with a small excess of coumarin to give the corresponding 3-perfluoroalkylated coumarins (3a-e), while poly-perfluoroalkylation of coumarin occurred when excess 2 was used in the reaction, and 3,6-diperfluoroalkylcoumarins (4) and 3,6,8-triperfluoroalkylcoumarins (5) were isolated as major products according to the ratio of starting materials.
