the high cost, toxicity or environmental impact of commonly used polyfluoroalkylation reagents. We report the sulfuryl fluoride (SO2F2)-mediated N-polyfluoroalkylation of weakly nucleophilic nitrogencompounds from readily available fluorinated alcohols. This method opens access to a variety of N-polyfluoroalkylated building blocks that are highly valuable for life science applications.
由于常用多氟烷基化试剂的高成本、毒性或环境影响, N-多氟烷基化反应具有挑战性。我们报告了硫酰氟 (SO 2 F 2 ) 介导的弱亲核氮化合物的N -多氟烷基化,这些化合物来自现成的氟化醇。该方法开启了对各种N-多氟烷基化构建块的访问,这些构建块对生命科学应用具有很高的价值。

A synthetic methodology for the specific conversion of primary aromatic amines into their N-monomethyl derivatives under very mild conditions is presented. Anilines are treated with 4-nitrobenzenesulfonyl (nosyl) chloride to generate the corresponding sulfonamides 2 in high yields. The subsequent N-methylation reaction of the sulfonamides 2 with a solution of diazomethane is rapid and quantitative
