Starting from RfH (1) [R-f=1,3,5-tris(trifluoromethyl)phenyl] RfNH2 (6
) is obtained in a four-step synthesis. The amine 6 reacts with chloro
trimethylsilane in the presence of DBU (1,8-diazabicyclo(5,4,0)undec-7
-ene) forming the monosilylated and the bissilylated amines 7 and 8. T
he potassium salt of 7 reacts with SiCl4 yielding RfN(SiCl3), (10). Th
e single crystal X-ray structure of 10 is reported. (C) 1998 Elsevier
