- ItemN,N ' and N,O chelated phosphenium cations containing aminotroponiminate or aminotroponate units(ELSEVIER SCIENCE SA, 2009) Pop, Lucian Cristian; Katir, Nadia; Castel, Annie; Silaghi Dumitrescu, Luminita; Delpech, Fabien; Silaghi Dumitrescu, Ioan; Gornitzka, Heinz; MacLeod Carey, Desmond; Saffon, NathalieNew phosphenium cations stabilized by bidentate monoanionic N-isopropyl-2-(isopropylamino)troponiminate or 2-(isopropylamino)troponate units have been synthesized. These complexes were characterized by P-31, H-1 and C-13 NMR spectroscopies, and the molecular structures were determined by X-ray crystallography. These data indicate the formation of N,N'- and N,O-chelate derivatives having three-coordinate phosphorous atoms included in planar heterobicycles. Moreover, computational studies support the presence of high delocalization of the positive charge into the pi-conjugated carbon backbone and of the high-lying phosphorus lone-pair orbital.

- ItemNew Rh derivatives of s-indacene active in dehydrogenative silylation of styrene(ELSEVIER SCIENCE SA, 2006) Esponda, Edgardo; Adams, Christopher; Burgos, Francisco; Chavez, Ivonne; Manriquez, Juan M.; Delpech, Fabien; Castel, Annie; Gornitzka, Heinz; Riviere Baudet, Monique; Riviere, PierreThe mono- and bimetallic complexes [(2,6-diethyl-4,8-dimethyl-s-indacenide){Rh(COD)}] (1), anti-[(2,6-diethyl-4,8-dimethyl-s-indacenediide) {Rh(COD)}(2)] (2a), syn-[(2,6-diethyl-4,8-dimethyl-s-indacenediide){Rh(COD)}(2)] (2b) were synthesized and characterized spectroscopically and in the case of complex 2b, by means of X-ray diffraction. The C-13 and Rh-103 NMR studies suggest that the bonding mode of the indacenediide ligand can be described as intermediate between eta(3)- and eta(5)-coordination. This result was confirmed by the crystal structure of 2b as evidenced by the slippage of the rhodium atom towards the periphery of the ligand. Cyclic voltammetry studies revealed a strong intermetallic communication through the fused ring ligand. This property was further illustrated by higher activity and selectivity of binuclear complexes 2 for the catalytic dehydrogenative silylation of styrene. (c) 2006 Elsevier B.V. All rights reserved.

- ItemSynthesis and structure of some heterobimetallic complexes having a polyalkyl-s-indacenyl spacer(ELSEVIER SCIENCE SA, 2013) Morales Verdejo, Cesar; Martinez, Ivan; Mac Leod Carey, Desmond; Chavez, Ivonne; Manuel Manriquez, Juan; Matioszek, Dimitri; Saffon, Nathalie; Castel, Annie; Riviere, Pierre; Molins, EliesThree heterobimetallic complexes LmM(s-Ic')M'Ln (M = Fe, Ru or Mn; M' = Ni) having the same Cp* nickel moiety and based on a polyalkyl-s-indacenyl spacer (s-Ic' = 2,6-diethyl-4,8-dimethyl-s-indacenyl) were synthesized by reacting Cp* Ni(acac) with the lithium derivative of the parent monometalated complex. All three compounds were fully characterized and shown to adopt a trans geometry by X-ray crystallography. (C) 2012 Elsevier B. V. All rights reserved.
