Abstract
The preparation of cis-[Rh(aa)2Cl2]+(aa = 2,2′-bipyridyl or 1,10-phenanthroline) has been re-examined and shown to be catalytic. The preparation and characterisation of cis-[Rh(aa)2X2]n+(X = I–, CN–, H2O, and NH3) and cis-[Rh(aa)2ClY]m+(Y = H2O, NH3, pyridine, and NO2 –) is described and the possible mechanisms of base hydrolysis and of substitution by cyanide and by iodide into cis-[Rh(aa)2Cl2]+ are discussed; the effect of dioxygen on these substitutions is also discussed. The resolution of cis-[M(aa)2Cl2]+(M = Rh or Ir) into optical isomers is described and their stability is discussed. A convenient catalytic preparation of [Rh(aa)3]3+ is given.Keywords
