【摘要】 <正> 由于氟原子的独特性质, 含氟有机化合物,特别是含氟生物活性物质的合成,近来愈来愈引起人们的兴趣。利用卤代二氟乙酸酯（XCF₂CO₂R,X=Br、Ⅰ）在分子中引入CF₂基团已有不少报道,但其合成方法报道不多,且条件过于剧烈。本文从易得的全氟乙磺内酯出发,通过分解N,N-二烷基-α-卤磺更多还原

【Abstract】 N,N-dialkyl-a-halosulfonyldifluoroacetamides （R¹R²NCOCF₂SO₂X 5, X=C1; 6, X=Br） were prepared by aminolysis, reduction and halegenation of perfluoroethane sultone. Their properties were studied briefly and N, N-dialkylhalodifluoroacetamides （XCF₂CONR¹R², X=Cl, Br, I） were synthesized from them in good yield.更多还原
