  • C−F Bond Cleavage by Intramolecular S<sub>N</sub>2 Reaction of Alkyl Fluorides with O- and N-Nucleophiles

    日期:2009.4.3
    The nucleophilic substitution of alkyl fluorides was achieved in the intramolecular reactions with O- and N-nucleophiles. The intramolecular defluorinative cyclization reaction was influenced by the nature of nucleophiles, the size of the ring to be formed, and the comformational rigidity of the precursors. Intermolecular nucleophilic substitution reactions of alkyl fluorides under similar reaction
    在与O-和N-亲核试剂的分子内反应中实现了烷基氟化物的亲核取代。分子内脱氟环化反应受亲核试剂的性质,要形成的环的大小以及前体的构象刚性的影响。发现在相似的反应条件下烷基氟化物的分子间亲核取代反应是困难的。当前C-F键断裂反应的立体化学研究显示出完全的构型反转,这支持了分子内S N 2反应机理。
