Reactions of tris(pentafluorophenyl)silanes RSi(C6F5)3 with salicylaldehyde and secondary amines were studied. The reactions afforded α-pentafluorophenyl-substituted amines. Silanes RSi(C6F5)3 (R = Me, Ph, C6F5, CH2CH=CH2, and CH=CH2) were found to be efficient reagents for transfer of the C6F5 group to the iminium cation generated from salicylaldehyde and amine. However, tris(pentafluorophenyl)phenylethynyl-and tris(pentafluorophenyl)silanes were not able to serve as a source of a fluorinated substituent because of competitive transfer of acetylenide fragment or hydride.
