    Notes: Synthesis of Imidodiphosphates of Aluminum, Gallium, Indium, Tin, and Titanium.Me3SiN[P(O)Cl2]2, (1) and Me3SnN[P(O)Cl2]2 (2) are synthesized from NaN[P(O)Cl2]2 and Me3SiCl or Me3SnCl, respectively. Treatment of 1 with AlCl3, GaCl3 InCl3, Me2SnCl2, and TiCl4 yields (3), (4), (5), (6), and (7), respectively. Reaction of LiN[P(O)Ph2]2 with TiCl4 leads to (8). NMR spectra demonstrate that the tetrachloroimidodiphosphate ligand coordinates through the oxygen atoms towards the metal atom.

    Notes: New Perrhenates and Aminorhenium Trioxides with Elements of Group 14. and 15. of the Periodic SystemNew perrhenates have been prepared by reaction of Re2O7 with triphenylstibin oxide and di-n-butyltin oxide, respectively. The single-crystal X-ray structure of Ph3Sb(OReO3)2 (1) is reported. The reaction of Ph3SbO and nBu2SnO with Re2O7 in 1:2 molar ratio gives (O3ReOSbPh3)2O (2) and [O3ReOSn-(nBu)2]2O (3), respectively. A trimethylstannyl-substituted aminorhenium trioxide (Me3Sn)2NReO3 (4) has been prepared by reaction of Me3SiOReO3 and N(SnMe3)3.

    Description / Table of Contents: Inorganic Ring System Containing Ferrocenyl SubstituentsThree-, four-, five-, and eight-membered heterocycles are synthesized starting from FcPCl2 (1), FcPH2 (2), FcAsCl2 (3) and Fe(C5H4AsCl2)2 (4) (Fc = Ferrocenyl). Treatment of 1 with 2 in the presence of DBU yields (FcP)n, which reacts with (Ph3P)2Pt(C2H4) to give (7). The corresponding As2Pt ring system 9 is available in high yield via (FcAs)3 (8). The reduction of 1 with LiAlH4 yields (FcP)4 (10). A five-membered arsenic sulfur heterocycle, Fc2As2S3 (12), is formed in the reaction of FcAs=P(2,4,6-tBu3C6H2) (11) with sulfur. FcAsCl2 (3) reacts with Me3SiNSNSiMe3 to give FcAs(NSN)2AsFc (13), which contains an eight-membered As2S2N4 ring. Its complexation with (norbornadiene)M(CO)4 leads to the tetracarbonyl complexes [FcAs(NSN)2AsFc]M(CO)4 (14, 15; M = Cr, Mo). An arsenic-bridged ferrocenophane 16 can be isolated from the reaction of Fe(C5H4Li)2 x TMEDA with AsCl3. The reaction of 4 with Me3SiNSNSiMe3 also produces a condensed ferrocenophane derivative, (C5H4)2FeAs2N6S4 (17). The molecular structures of 13 and 17 have been determined by X-ray diffraction.
    Notes: Ausgehend von FcPCl2 (1), FcPH2 (2), FcAsCl2 (3) und Fe(C5H4AsCl2)2 (4) werden drei-, vier-, fünf- und achtgliedrige Heterocyclen mit Ferrocenyl-Substitutenten synthetisiert (Fc = Ferrocenyl). Durch Umsetzung von 1 mit 2 in Gegenwart von DBU entsteht (FcP)n, das mit (Ph3P)2Pt(C2H4) zu (7) reagiert. Der analoge As2Pt-Ring 9 ist über (FcAs)3 (8) in guter Ausbeute zugänglich. Die Reduktion von 1 mit LiAlH4 liefert (FcP)4 (10). Ein fünfgliedriger Arsen-Schwefel-Heterocyclus, Fc2As2S3 (12), entsteht durch Umsetzung von FcAs=P(2,4,6-tBu3C6H2) (11) mit Schwefel. FcAsCl2 (3) reagiert mit Me3SiNSNSiMe3 zu FcAs(NSN)2AsFc (13), das einen achtgliedrigen As2S2N4-Ring enthält. Dessen Komplexierung mit (Norbornadien)M(CO)4 führt zu den Tetracarbonyl-Komplexen [FcAs(NSN)2AsFc]M(CO)4 (14, 15; M = Cr, Mo). Ein Arsenüberbrücktes Ferrocenophan 16 kann bei der Reaktion von Fe(C5H4Li)2 × TMEDA mit AsCl3 isoliert werden. Auch die Umsetzung von 4 mit Me3SiNSNSiMe3 liefert ein kondensiertes Ferrocenophan-Derivat der Zusammensetzung (C5H4)2FeAs2N6S4 (17). Die Molekülstrukturen von 13 und 17 wurden röntgenographisch bestimmt.
