%X reaction of the dinuclear complex [{(h5-c5me5)rhcl} 2(¦̀-cl)2] with the chiral phosphine (r)-ph2pch2chmech2 oh leads to the complex [{(h5-c5me5)rhcl 2(h1-ph2pch2 chmech2oh-p)](1). this reaction, in the presence of agbf4, yields the cationic compound [{(h5-c5me5)rhcl(h 2- ph2pch2chmech2oh-p,o)]bf 4(2). variable-temperature 1h nmr and circular dichroism experiments support the stereoselective h2-chelate coordination of the ligand and the proposed configuration for the metal centre. in a similar way, the reaction of the dimer [{(h6-c6me6)rucl} 2(¦̀-cl)2] with the ligands (r)- and (s)-ph2pch2chmech2 oh afford the neutral complexes [(h6-c6me6)rucl 2{h1-pph2ch2 chmech2oh-p}] [r-ligand (3), s-ligand (4)], which in turn react with agbf4 to give the cationic compounds [(h6-c6me6)rucl{h 2-pph2ch2chmech2 oh-p,o}]bf4 [r-ligand (5), s-ligand (6)]. all complexes have been characterised by elemental analysis, ir and multinuclear nmr spectroscopies
