  • The hydride complex RuH(BH{sub 4})(Cyttp) was produced from the reaction of RuCl{sub 2}(Cyttp) with excess NaBH{sub 4}. A series of six-coordinate RuHCl(L)(Cyttp) complexes (L = CO, P(OMe){sub 3}, CH{sub 3}CN) were synthesized from RuHCl(Cyttp), which was prepared from the reaction of RuCl{sub 2}(Cyttp) and excess lithium hydride in THF. Ruthenium dihydride complexes RuH{sub 2}(L)(Cyttp) (L = CO, N{sub 2}, CNCH{sub 2}C{sub 6}H{sub 5}, P(OMe){sub 3}, and P(OPh){sub 3}) were synthesized from RuH{sub 2}(H{sub 2})(Cyttp), which was prepared from the reaction of RuCl{sub 2}(Cyttp) with NaH in THF under a H{sub 2} atmosphere. The new compounds were characterized by microanalyses andmore » infrared and {sup 1}H and {sup 31}P NMR spectroscopy. The crystal structure of RuII{sub 2} (N{sub 2})(Cyttp) was determined and is reported here.« less
  • The synthesis of the ligand 1,4,7-tris(3-aminopropyl)-1,4,7-triazacyclononane(tapacn) can be achieved by the reaction of 1,4,7-triazacyclononane with an excess of acetonitrile, followed by reduction of the nitrile with sodium metal in toluene. Halide salts of the cobalt(III)(complex A) and nickel(II)(complex B) ions have been prepared and examined by using x-ray crystallography. The crystal structures are reported. The /sup 13/C NMR spectrum of the dismagnetic d/sup 6/ Co(III) complex ion is reported. A discussion of the two ligand structures deals with the ligand opening and with trigonal twist angle as related to metal ion size and mechanism for redox processes of the complex.more » 45 refs., 6 figs., 9 tabs.« less
  • The complexes [(PiPr[sub 3])[sub 2](CO)HM([mu],[eta][sup 4]-BH[sub 4])MH(CO)(PiPr[sub 3])[sub 2]]BF[sub 4] (5, 6), MH([eta][sup 2]-O[sub 2]CR[sup *])(CO)(PiPr[sub 3])[sub 2] (7-13) and MH(pz)(CO)(Hpz)(PiPr[sub 3])[sub 2] (14, 15) (M = Os, Ru) have been prepared by reaction of MH([eta][sup 2]-H[sub 2]BH[sub 2])(CO)(PiPr[sub 3])[sub 2] (M = Os, Ru) with HBF[sub 4], R[sup *]CO[sub 2]H (R[sup *] = (S)-CH(NaphOMe)Me, (R)-CH(OMe)Ph, (R)-C(CF[sub 3])(OMe)Ph, (S)-[ovr CHOC([double bond]O)CH[sub 2]C]H[sub 2]) and Hpz (pyrazole), respectively. 5 and 6 react with molecular hydrogen, tetrafluorobenzobarrelene (TFB), methyl vinyl ketone, acetonitrile, and acetone to give [OsH([eta][sup 2]-H[sub 2])(CO)(PiPr[sub 3])[sub 2]][sup +] (16), [OsH([eta][sup 2]-H[sub 2])(CO)(OH[sub 2])(PiPr[sub 3])[sub 2]][sup +] (17), [OsH(CO)(TFB)(PiPr[submore » 3])[sub 2]][sup +] (18), [[ovr OsH(CO)([pi]-CH[sub 2][double bond]CHC([double bond]O])CH[sub 3])(PiPr[sub 3])[sub 2]][sup +] (19), [MH(CO)(CH[sub 3]CN)[sub 2](PiPr[sub 3])[sub 2]][sup +] (M = Os (20), Ru (21)) and [RuH(CO)([eta][sup 1]-(CH[sub 3])[sub 2]CO)[sub 2](PiPr[sub 3])[sub 2]][sup +] (22). In solution 22 dissociates an acetone molecule to give [RuH(CO)([eta][sup 1]-(CH[sub 3])[sub 2]CO)(PiPr[sub 3])[sub 2]][sup +] (23). The cations [MH(CO)(Hpz)[sub 2](PiPr[sub 3])[sub 2]][sup +] (M = Os (24), Ru (25)) were obtained by addition of HBF[sub 4] to diethyl ether solutions of 14 and 15. The latter react with HCl to give a mixture of two isomers of MHCl(CO)(Hpz)(PiPr[sub 3])[sub 2] (M = Os (26), Ru (27)). The catalytic activity of 7-13 in asymmetric hydrogen transfer from 2-propanol to acetophenone is also described. The osmium carboxylates lead to considerably higher optical yields than ruthenium complexes. 31 refs., 5 figs.« less
  • A series of [eta][sup 1](E)-coordinated (E = S or Se) thiophene, benzo[b]thiophene and selenophene complexes [Cp(NO)(PPh[sub 3])Re([eta][sup 1](E)-L)][sup +], Cp = C[sub 5]H[sub 5], L = thiophene (T), 2-methylthiophene (2-MeT), 2,5-dimethylthiophene (2,5-Me[sub 2]T), benzo[b]thiophene (BT), 3-methylbenzo[b]thiophene (3-MeBT), selenophene (Sel), 2-methylselenophene (2-MeSel), and 2,5-dimethylselenophene (2,5-Me[sub 2]Sel) are prepared by the reaction of [Cp(NO)(PPh[sub 3])Re(ClC[sub 6]H[sub 5])][sup +] with the appropriate ligand. The T, 2-MeT, BT, 3-MeBT, Sel, 2-MeSel complexes are deprotonated at C(2) by strong, non-nucleophilic bases to give the neutral Cp(NO)(PPh[sub 3])Re(2-L-yl) complexes, where 2-L-yl = 2-thienyl (2-Tyl), 2-5(methylthienyl) (2-(5-MeTyl), 2[minus]benzothienyl (2-BTyl), 2-(3-methylbenzothienyl) (2-3-MeBTyl)), 2-selenyl (2-Selyl), and 2-(5-methylselenyl) (2-5-MeSelyl). Themore » pK[sub a] of the base required to effect this deprotonation increases with the L ligand in the complex in the following order: Sel < T < BT. The 2-Tyl, 2-BTyl and 2-Selyl complexes react with either HBF[sub 4][center dot]Et[sub 2]O or HO[sub 3]SCF[sub 3] at [minus]42[degrees]C to give the corresponding carbene complexes [Cp(NO)(PPh[sub 3])Re(2-L-ylcarbene)][sup +] resulting from protonation at C(3). 43 refs., 2 figs., 5 tabs.« less
  • Permethylated Cp*{sub 2}NbS{sub 3}H (2; Cp* = C{sub 5}Me{sub 5}) and the Ta complex Cp{prime}{sub 2}TaS{sub 2}H(3) were synthesized and structurally investigated by X-ray diffraction. 2 and 3 possess M({eta}{sup 2}-S{sub 2}) cores to which either an SH (2) or a H (3) is attached. Complex 3 loses sulfur upon reaction with PR{sub 3} (R = C{sub 6}H{sub 5}, OCH{sub 3}) and CH{sub 3}I to form compounds 4 and 5, which both contain the Ta{double_bond}S moiety. 26 refs., 2 figs., 5 tabs.
