  Tetramethylphospholyluranium complexes and their pentamethylcyclopentadienyl analogues

  摘要：

  The mono- and bis-(tetramethylphospholyl)uranium complexes [U(tmp)(Cl)(3)(L)(2)] (tmp = C(4)Me(4)P, L = tetrahydrofuran or L(2) = dimethoxyethane), [U(tmp)(X)(3)] (X = BH4, CH(2)Ph) and [U(tmp)(2)(X)(2)] (X = Cl, BH4, alkyl, or alkoxide) were compared with their pentamethylcyclopentadienyl (cp*) analogues. The crystal structures of [U(tmp)(Cl)(3)(dimethoxyethane)] and [U(cp*)(2)(BH4)(2)] have been determined. Although the structures of the phospholyl compounds are similar to those of their cyclopentadienyl counterparts, the distinct electronic effects of the tmp and cp* ligands (tmp being less electron-donating than cp*) are manifest in the coordinating and redox properties of the complexes.

  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.

  The phospholyl nickel compound [Ni(eta(5)-C(4)Me(4)P)(mu-eta(1)-C(4)Me(4)P)}(2)] 1 was prepared by treating NiCl2 with two equivalents of KC(4)Me(4)P in pyridine, whereas reaction of NiCl2 with two equivalents of [U(eta(5)-C(4)Me(4)P)(3)Cl] or an excess of [U(eta(5)-C(4)Me(4)P)(2)Cl-2] afforded the trinuclear complex [Ni(mu-eta(5),eta(1)-C(4)Me(4)P)(2)UCl2}(2)] 2. Reduction of a 1:2 mixture of 1 and [U(eta(5)-C(4)Me(4)P)(2)Cl-2] by sodium amalgam in tetrahydrofuran gave the tetranuclear compound [Ni-2(mu-eta(1)-C(4)Me(4)P)(2)}(mu-eta(5),eta(1)-C(4)Me(4)P)(2)UCl2}(2) . 3C(4)H(8)O] 3. The crystal structures of 1, 2 and 3 have been determined.
