                                摘要:
                                The treatment of optically P-chiral tetraphosphine, (3S, 6R, 9R, 12S)-6,9-di-tert-butyl-2,2,3,12,13,13-hexamethyl3,6,9,12-tetraphosphatetradecane (1), with rhodium(I), palladium(II), and ruthenium( II) complex precursors led to the selective formation of mono-, di-, or trinuclear homo- or heterometallic complexes, [Rh(1)]SbF6 (4), [{Rh(nbd)}(2)(1)](SbF6)(2) (3), [{Pd(eta(3)-allyl)} 2(1)](SbF6)(2) (5), [{RuCl(eta(5)-C-5(CH3)(5))}(2)(1)] (6), and [{RuCl2(eta(6)-benzene)}(2)(PdCl2)(1)] (8). These complexes were characterized by NMR and X-ray crystallographic analysis. (C) 2008 Elsevier B. V. All rights reserved.
