Vaska-type complexes such as MCl(CO)L2 (M = Rh or Ir, L = tertiary phosphine) or the Wilkinson complex RhCl(PPh3)3 underwent halogen exchange reactions with halosilanes Me3SiX (X = Br, I) to give MX(CO)L2 or RhX(PPh3)3 respectively with the formation of Me3SiCl. The reaction of RhH(CO)(PPh3)3 with MeSiCl3 also afforded RhCl(CO)(PPh3)2.
