Trifluoromethanesulfonato complexes of cis and trans-bis(ethylenediamine)rhodium(III) have been used to prepare new complexes of Rh(III). Starting with cis-[(en)2Rh(OSO2CF3)2]+, several complexes coordinated by bidentate urea ligands such as N-2-pyridylmethyl-N'-phenylurea have been prepared. Trans-[(en)2Rh(OSO2CF3)Cl]+ has been reacted with butylamine to produce the butylamine chloro complex. This can then be treated with trifluoromethanesulfonic acid to remove the chloride. Subsequent reactions with other ligands produce a variety of new complexes (see Eqn). Details of their synthesis and characterization will be described.
