  Synthesis of Phospholyl-Bridged Heterobimetallic Ruthenium Hydrides in Combination with Zirconium and Ytterbium and the Crystal Structure of (THF)₂Yb[μ(η⁵,η¹)-C₄Me₄P]₂Ru(H)₂(Ph₃P)₂

  摘要：

  Heterobimetallic zirconium-ruthenium and ytterbium-ruthenium dihydrides, having bridging phospholyl ligands, have been obtained for the first time. Reaction of bin(eta(5)-tetramethylphospholyl)dichlorozirconium [(TMP)(2)ZrCl2] with RuH4(PPh(3))(3) gave the zirconium-ruthenium heterobimetallic Cl2Zr[mu(eta(5),eta(1))-TMP]Ru-2(H)(2)(PPh(3))(2). This compound was transformed into the hydridochloride Cl2Zr[mu(eta(5),eta(1))-TMP]Ru-2(H)(Cl)(PPh(3))(2) by the action of CCl4. Similarly, reaction of [(TMP)(2)Yb] with RuH4(PPh(3))(3) afforded (THF)(2)Yb[mu(eta(5),eta(1))-TMP]Ru-2(H)(2)(PPh(3))(2). The structure of this compound, which has been determined by X-ray crystallography, confirms the trans configuration of the dihydride deduced previously from NMR data. Attempts to isolate products from the reaction of [(TMP)(2)UCl2] or [(TMP)(2)U(BH4)(2)] with RuH4(PPh(3))(3) were unsuccessful, but NMR data show the formation of both heterobimetallic trans- and cis-ruthenium dihydride-uranium compounds X(2)U[mu(eta(5),eta(1))-TMP]Ru-2(H)(2)(PPh(3))(2) (X = BH4, Cl) in solution.

  Phospholyl (phosphacyclopentadienyl) and arsolyl (arsacyclopentadienyl) complexes of ytterbium(II) and samarium(II). Synthetic, structural and multinuclear (31P and 171Yb) NMR studies

  摘要：

  Bis(eta5-phospholyl) or bis(eta5-arsolyl)M(THF)2 complexes, where M = Sm or Yb, can be obtained either by reaction of potassium phospholides or arsolides with MI2(THF)2 or by cleavage of the P-P or As-As bond of a biphospholyl or biarsolyl by ytterbium or samarium metal powders. The THF molecules that coordinate to the metal are labile when the ligands are 2,3,4,5-tetramethylphospholyl or arsolyl, but not when they are 2,5-diphenylphospholyl. An X-ray crystal structure of bis(eta5-2,5-diphenylphospholyl)Yb (THF)2 is Presented. Yb-171 and P-31 NMR studies reveal that exchange of ligands is occurring in bis(eta5-2,3,4,5-tetramethylphospholyl)Yb(THF)2; this exchange is slow at room temperature and frozen at -20-degrees-C. For bis(eta5-2,5-phenyldiphenylphospholyl)Yb(THF)2 P-31 NMR data suggest that no exchange is occurring at room temperature.
