Attempts to prepare alkylidyne-trirhodium cluster complexes by reaction of Na with CX4, CHX3 (X = Cl or Br) and CCl3CF3 have resulted only in the formation of .With CHCl3 at -20 deg C the major product is 2, though to be formed by decomposition of .Reaction between Na and perfluoroacyl chlorides has given the new compounds F)(CO)2(PPh3)2> (R_F = CF3, C2F5 and C3F7), which do not decarbonylate even after 6-9 days at 120 deg C.Tetrafluoroethylene has been found to react with under UV irradiation conditions to give in 33percent yield.The latter does not react with to form clusters, but surprisingly, its reaction with Na resulted in a low yield of CF3CCo3(CO)9; under similar conditions Na caused only decomposition.
