RhCl(PMe3)3 reacts with HSiPh3 to give mer-RhCl(H)(SiPh3)(PMe3)3 (1), whose X-ray structure shows octahedral coordination around the Rh(III) center with trans chloro and triphenylsilyl ligands. Reaction of HSi(C6H4CF3-p)3 with RhCl(PMe3)3 gives a mixture of Rh(III) complexes mer-RhCl(H){Si(C6H4CF3-p)3}(PMe 3)3 (2), fac-RhH2(Si(C6H4CF3-P) 3}(PMe3)3 (3), and cis,mer-RhCl2(H)(PMe3)3 (4) with relative amounts that depend on the specific reaction conditions. X-ray crystallography of 2 shows that the Si(C6H4CF3-P)3 ligand is cis to both the H and Cl ligands. The differing chemical reactivity of 2 and 1 indicates the importance of the cis-configuration for reductive elimination of HSiAr3 and ClSiAr3 from the complexes.
