    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.
