Ph3—nClnGeM′ (n = 1 or 2), while the analogous silicon compounds were prepared by the reaction of the appropriate phenylchloro- or phenylfluorophenyl-silane with the transition metal carbonyl dimers. The reactivities of the compounds Ph3—nClnMM′ [n = 1 to 3; M = Si, Ge or Sn and M′ = Mn(CO)5 or Fe(CO)2Cp] towards pentafluorophenyllithium have been found to depend upon M, M′ and teh number of phenyl groups bonded
