    Description / Table of Contents: Organoruthenaboran-Chemie. IX. Die Reaktion von [{(η6-C6Me6)RuCl2}2] und [{(η6-MeC6H4-4-iPr)RuCl2}2] mit dem [nido-B9H12]--AnionDie Reaktion zwischen [NnBu4][nido-B9H12] und [{(η6-C6Me6)RuCl2}2] in CH2Cl2-Lösung ergibt [5-Cl-6-(η6-C6Me6)-nido-6-RuB9H12] (12%), [6-(η6-C6Me6)-nido-6-RuB9H13] (1%) und [1-(η6-C6Me6)-isocloso-1-RuB9H9] (2%). Die entsprechende Reaktion mit dem p-Cymol-Analogon [{(η6-MeC6H4-iPr)RuCl2}2] ergibt [5-Cl-6-(η6-MeC6H4-4-iPr)-nido-6-RuB9H12] (15%), [6-(η6-MeC6H4-4-iPr)-nido-6-RuB9H13] (1%) und [1-(η6-MeC6H4-4-iPr)-isocloso-1-RuB9H9] (3%). Die Produkte sind gelbe, luftstabile Festkörper; sie wurden chromatographisch getrennt und massenspektroskopisch und NMR-spektroskopisch charakterisiert.
    Notes: Reaction between [NnBu4][nido-B9H12] and [{(η6-C6Me6)RuCl2}2] in CH2Cl2 solution yields [5-Cl-6-(η6-C6Me6)-nido-6-RuB9H12] (12%), [6-(η6-C6Me6)-nido-6-RuB9H13] (1%), and [1-(η6-C6Me6)-isocloso-1-RuB9H9] (2%). The corresponding reaction with the p-cymene analogue [{(η6-MeC6H4-4-iPr)RuCl2}2] yields [5-Cl-6-(η6-MeC6H4-4-iPr)-nido-6-RuB9H12] (15%), [6-(η6-MeC6H4-4-iPr)-nido-6-RuB9H13] (1%), and [1-(η6-MeC6H4-4-iPr)-isocloso-1-RuB9H9] (3%). The products were all yellow, air-stable solids; they were separated by chromatography and characterized by mass spectrometry and n.m.r. spectroscopy.

    Description / Table of Contents: Organoruthenaboran-Chemie. X. Die SMe2-katalysierte Bildung von [1-(η6-C6Me6)-isocloso-RuB9H9] und einige B-Phenylamino-Derivate. NMR- und Röntgen-UntersuchungenDie Einwirkung von SMe2, auf das zehneckige nido-Ruthenaboran [1-(η6-C6Me6)RuB9H13] (1) führt in hoher Ausbeute zum unsubstituierten isocloso-Ruthenaboran [1-(η6-C6Me6)RuB9H9] (2). Die analoge Verbindung mit Benzol [1-(η6-C6Me6)RuB9H9] wird entsprechend erhalten. Im Gegensatz dazu führt die Reaktion von (1) mit PhNH2 zu einer Reihe von B-Phenylamino-isocloso-Derivaten wie [1-(η6-C6Me6)-2-(PhNH)-isocloso-1-RuB9H8] (3) (orange Kristalle), [1-(η6-C6Me6)-2,3-(PhNH)2-isocloso-1-RuB9H7] (4) (rotorange) und [1-(η6-C6Me6)-5,6,7-(PhNH)3-isocloso-l-RuB9H6] (5) (dunkelrot). Detaillierte 1H- und 11B-NMR-Spektren werden angegeben. Die Struktur von (3) wird durch eine Einkristall-Röntgen-Strukturanalyse des Solvats [1-(η6-C6Me6)-2-(PhNH)-isocloso-1-RuB9H8] · 1/2 CH2C12 ermittelt; die Kristalle sind monoklin, Raumgruppe C2/c, mit a = 1895,1(3), b = 1556,6(3), c = 1716,4(3)pm, β = 104,37(1)° und Z = 8.
    Notes: The action of SMe2 on the ten-vertex nido-ruthenaborane [6-(η6-C6Me6)RuB9Hl3] (1) provides a high-yield route to the unsubstituted isocloso-ruthenaborane [1-(η6-C6Me6)RuB9H9] (2). The benzene analogue [1-(η6-C6Me6)RuB9H9] is prepared similarly. By contrast, reaction of (1) with PhNH2 gives a variety of B-phenylamino isocloso derivatives, including orange crystals of [1-(η6-C6Me6)-2-(PhNH)-isocloso-1-RuB9H8] (3), red-orange [1-(η6-C6Me6)-2,3-(PhNH)2-isocloso-1-RuB9H7] (4) and dark-red [1-(η6-C6Me6)-5,6,7-(PhNH)3-isocloso-1-RuB9H6] (5). Detailed 1H and 11B nmr properties of these various compounds are described. The structure of (3) has been established by a single-crystal X-ray diffraction study of the solvate [1-(η6-C6Me6)-2-(PhNH)-isocloso-1-RuB9H8] · 1/2 CH2Cl2; the crystals were monoclinic, space group C2/c, with a = 1895.1(3), b = 1556.6(3), c = 1716.4(3) pm, β = 104.37(1)° and z = 8.
