    Description / Table of Contents: Organoruthenaboran Chemie. VIII. Die Reaktionen von [{(η6-C6Me6)RuCl2}2] und [{(η6-MeC6H4Pr)RuCl2}2] mit Cs[arachno-6-SB9H12]: Isolierung von zehn-, elf- und zwölfeckigen Ruthenathiaboranen und ihre Charakterisierung durch NMR-SpektroskopieDie Reaktion von [{(η6-C6H6)RuCl2}2] mit arachno-[6-SB9H12]- und NaH in CH2Cl2/Aceton-Lösung ergibt in niedriger Ausbeute (1,3%) ein closo-zehneckiges Ruthenathiaboran, [2-(η6-C6Me6)-closo-2, 1-RuSB8H8], während die Reaktion des p-Cymolanalogon [{(η6-MeC6H4Pr)RuCl2}2] mit arachno-[6-SB9H12]- und N,N,N′,N′ Tetramethylnaphthalin-1,8-diamin(tmnd) in Aceton nido-elfeckige und closo-zwölfeckige Ruthenathiaborane folgender Formulierungen [11-Cl-7-(η6MeC6H4Pr)-nido-7, 8-RuSB9H10] (2,2%), [2,3-(η6-MeC6H4Pr)2 -closo-2,3,1-Ru2SB9H9] (21%), und [7-Cl-2, 3-(η6MeC6H4Pr)2-closo -2,3,1-Ru2SB9H8] (8%) ergibt. Die Produkte sind alle luftstabile, rote oder gelbe Festkörper und werden durch kernmagnetische Doppelresonanz und 2D-Korrelations-NMR-Spektroskopie (COSY) charakterisiert.
    Notes: Reaction of [{(η6-C6H6)RuCl2}2] with arachno-[6-SB9H12]- and NaH in CH2Cl2/acetone solution gives a low yield (1.3%) of a closo ten-vertex ruthenathiaborane formulated as [2-(η6-C6Me6)-closo-2,1-RuSB8 H8] whereas reaction of the p-cymene analogue [{(η6-MeC6H4Pr)RuCl2}2] with arachno-[6-SB9H12]- and N,N,N′,N′-tetramethylnaphalene-1,8-diamine (tmnd) in acetone yields nido-eleven-vertex and closo-twelve-vertex ruthenathiaboranes of proposed formulations [11-Cl-7-(η6MeC6H4Pr)-nido-7, 8-RuSB9H10] (2.2%), [2,3-(η6-MeC6H4Pr)2- closo-2,3,1-Ru2SB9H9] (21%), and [7-Cl-2,3-(η6-MeC6H4Pr)2 -closo-2,3,1-Ru2SB9H8] (8%). The products are all air-stable red or yellow solids and their characterization made use of nuclear magnetic double resonance and twodimensional correlation n.m.r. spectroscopy (COSY).
