Nucleophilic addition of the pentafluorophenyl group from (C6F5)3SiF to non-activated imines affording α-C6F5-substituted secondary amines in high yield has been described. The reaction proceeds via simultaneous activation of imines and the silane reagent by means of a proton and chlorideion, respectively.
已经描述了将来自(C 6 F 5)3 SiF的五氟苯基亲核加成到未活化的亚胺上,从而以高收率提供α- C6 F 5取代的仲胺。通过分别借助于质子和氯离子同时活化亚胺和硅烷试剂来进行反应。
