In the search for versatile reagents compatible with mechanochemical techniques, in this work we studied the reactivity of N-fluorobenzenesulfonimide (NFSI) by ball milling. We corroborated that, by mechanochemistry, NFSI can engage in a variety of reactions such as fluorinations, fluorodemethylations, sulfonylations, and amidations. In comparison to the protocols reported in solution, the mechanochemical reactions were accomplished in the absence of solvents, in short reaction times, and in yields comparable to or higher than their solvent-based counterparts.
在寻找与机械化学技术兼容的多功能试剂方面,在这项工作中,我们通过球磨研究了N-氟苯磺酰亚胺(NFSI)的反应性。我们证实,通过机械化学,NFSI可以参与各种反应,如氟化反应、去甲基氟化反应、磺酰化反应和酰胺化反应。与溶液中报道的方案相比,机械化学反应在无溶剂的情况下进行,反应时间短,收率与或高于基于溶剂的对应物。
