Construction of optically active multimetallic systems of rhodium(I), palladium(II), and ruthenium(II) with a P-chiral tetraphosphine ligand

Mono-, di-, or trinuclear homo- or heterometallic complexes of (3S,6R,9R,12S)-6,9-di-tert-butyl-2,2,3,12,13,13-hexamethyl-3,6,9,12-tetraphosphatetrad ecane were selectively prepared from rhodium(I), palladium(II), and ruthenium(II) complex precursors. These complexes were characterized by NMR and X-ray crystallographic analysis.
