1,3-Bis(polyfluoroalkyl)- and 1-mesityl-3-(polyfluoroalkyl)imidazolium salts differing in the length of a polyfluorinated chain and a non-fluorinated spacer were synthesized as key building blocks for fluorous NHC (N-heterocyclic carbene) ligands. A newapproach using polyfluoroalkyl triflates instead of the corresponding iodides was employed allowing fine tailoring of fluorous properties, as well

PH(3) and commercially available H(2)C=CHR(f) (R(f6)(/)(8)(/)(10) = (CF(2))(5)CF(3)/(CF(2))(7)CF(3)/(CF(2))(9)CF(3)) give, in two-stage processes conducted with free radical initiators (AIBN, VAZO; 80-90 degrees C), the phosphines P(CH(2)CH(2)R(f))(3) (1-3; 63-75%). Analogous reactions with H(2)C=CHCH(2)R(f8) (7) and H(2)C=CHCH(2)CH(2)R(f8) (10) give P(CH(2)CH(2)CH(2)R(f8))(3) (4, 73%) and P(CH(2)
