Using acetonitrile or DMF as cosolvent, both perfluoroalkyl iodides such as Cl(CF_2)_nI(n=4,6,8, 1a-1c), CF_3(CF_2)n I(n=5,6,7, 1d-1f), I(CF_2)_n O (CF_2)SO_3 Na (n=2,4,6, 1g-1i)and perfl-uoroalkyl bromides such as Cl(CF_2) n Br (n=4,6, 3a-3b) and C_7F_(15) Br (3e) reacted with Rongalitein aqueous solution to give the corresponding sulfinates Cl(CF_2)n SO_2 Na (n=4,6,8, 2a-2c), CF_3-(CF_2)n SO_2Na (n=5,6,7, 2d-2f) and NaO_2S(CF_2)n O(CF_2)_2 SO_3Na (n=2,4,6, 2g-2i) in moderateyields. 1H-perfluoroalkanes were formed as the main products when other solvents such as ethanol.iso-propanol, 1,4-dioxane and morpholine were used.
