  Diastereoselectivity in Chiral Osmium Complexes of a Bidentate Bisphosphine Monoxide Ligand

  摘要：

  The chelation of [(eta(6)-Cy)OsL] fragments (Cy = cymene; L = monodentate ligand) by bisphospkine monoxide ligands generates chiral-at-metal complexes. If the bisphosphine monoxide backbone contains a chiral center, diastereomeric products are formed. Osmium complexes of this type prepared using rac-Ph2PCH(Me)P(O)Ph-2 epimerize to form a preferred isomer in which the methyl group is distal to L. This has been observed for the analogous ruthenium complexes, but the interconversion of diastereomers occurs at a greatly reduced rate. The slower interconversion allows spectroscopic characterization of the thermodynamically less favored isomers, as the corresponding ruthenium species are tao short-lived for such investigations.

  Heterobidentate and hemilabile ligands involving P,O-donor chelates produce chiral metal centers when bound to arene-ruthenium complexes. This chirality in cymene complexes produces diastereotopic methyl groups in the isopropyl ligand which serve as a detector of the chirality at the metal. [CyRu(eta(2)-chelate-P,O)Cl](+) cations are precursors to strong 16-electron dicationic Lewis acids which have potential use in asymmetric catalysis. Sixteen-electron complexes of this type, however, provide a pathway with a low barrier to racemization or epimerization of the metal center in intermediates, such as [CyRu(eta(2)-chelate-P,O)(PhCHO)](2+). Substitution of the central carbon in diphenylphosphinomethane monoxide (dppmO) forces the ligand to adopt a configuration with the substituent in an endo position, thus forcing the 16-electron intermediate to return diastereoselectively to its original configuration and prevents epimerization. Thus, an X-ray structure shows that; (R-Ru*,R-C*)[CyRu(eta(2)- Ph2PCHR)Ph2PO-P,O)Cl](+) is the preferred diastereomeric pair. In the parent, [CyRu(eta(2)-dppmO-P,O)(ligand)](2+), racemization occurs at the metal center, since there is nothing driving the preferential formation of either the R or S ruthenium center. When the ligands are chiral, however, the metal center epimerizes to minimize steric interactions in the two diastereomers. The equilibrium between [(R-Ru)-CyRu(eta(2)-dppmO-P,O)(R-C-ligand)](2+) and [(S-Ru)-CyRu(eta(2)-dppmO-P,O)(R-C-ligand)](2+) reflects a 37% de for (1R)-(-)-myrtenal. Since a substituent on the central carbon prevents epimerization at the metal center, this diastereoselectivity is reflected in a preference for binding of (R-C)-ligand by either [(R-Ru,R-C)CyRu(eta(2)-Ph2PCHPr)Ph2PO-P,O)](2+) or [(S-Ru,S-C)-CyRu(eta(2)-Ph2PCHPr)Ph2PO-P,O)](2+). An X-ray structure of rac-[(R-Ru*,R-C)-CyRu(eta(2)-Ph2PCHPr)Ph2PO-P,O)(PhCHO](2+) shows that the aldehyde assumes an orientation that would suggest one stereoface of the aldehyde may be more susceptible to attack.

  The compounds [CyRu(eta (2)-Ph2PCH(Me)Ph2PO)L] [SbF6](2), where Cy = p-CH3C6H4CH(CH3)(2); L = pyridine, 2; 3,5-lutidine, 3; isoquinoline, 4, were synthesized by chloride abstraction from [CyRu(eta (2)-Ph2PCH(Me)Ph2PO)Cl] [SbF6], 1, followed by treatment of the intermediate Lewis acid [CyRu(eta (2)-Ph2PCH(Me)Ph2PO)][SbF6](2) with the appropriate ligand. Characterization by elemental analysis, H-1, P-31(H-1), VT NMR spectroscopy, and IR spectroscopy indicated that 2-4 were obtained as a mixture of exo and endo diastereomers (de = 14-60%). The endo diastereomer of compound 2 was also characterized by X-ray crystallography which revealed the (R-Ru*,R-C*) relative configuration of the two stereogenic centers within the molecule. In contrast to analogues with other neutral donors, P-31H-1} NMR spectroscopy experiments demonstrated that 2-4 were stable to diastereomer interconversion in solution. This suggests that epimerization of the ruthenium center in an intermediate exo-[CyRu(eta (2)-Ph2PCH(Me)Ph2PO)] [SbF6](2) occurred by a path unavailable to 2-4 by inversion of the Ru(eta (2)-Ph2PCH(Me)Ph2PO) ring.
