Starting from RfH (1)[Rf= l, 3, 5-tris (trifluoromethyl) phenyl] RfNH2 (6) is obtained in a four- step synthesis. The amine 6 reacts with chlorotrimethylsilane in the presence of DBU (J, 8- diazabicyclo (5, 4, 0) undec-7-ene) forming the monosilylated and the bissilylated amines 7 and 8. The potassium salt of 7 reacts with SiCl4 yielding RfN (SiCl3) 2 (10). The single crystal X-ray structure of 10 is reported.
