    N,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, Nathalie
    New 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.

    New 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, Pierre
    The 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.
