Boron-Nitrogen Compounds. XII. Reaction of Some Silicon-Nitrogen Compounds with Boron Derivatives

Abstract: Reactions of aminosilanes with some boron compounds have been investigated. N-Silylated mono-, bis-, and trisaminoboranes were prepared by transamination. A study of the interaction of bis(trimethylsilyl)amme with (dimethylamino)chlorophenylborane yielded a new type of bisborylamine.Noth6 did not isolate the aminoborane but observed

“…The most efficient access to higher oligo(iminoboranes) is by B À N coupling of chloroborane and silylamine precursors via ClSiMe 3 elimination. [10] The group of Helten has used this methodology to synthesize the first well-defined oligo(iminoboranes) (V) by polycondensation of 1,3-bis(trimethylsilyl)-1,3,2-diazaborolidine precursors with dichloro-(organo)boranes (Scheme 1 a). [11] Our group has also reported the coupling of two Cl 2 BN(SiMe 3 ) 2 molecules at [(C 5 H 5 )Ru(CO) 2 ]Na with elimination of NaCl and ClSiMe 3 , yielding the (N-aminoboryl)aminoboryl complex VI (Scheme 1 b).…”

“…Der effizienteste Zugang zu hçheren Oligo(iminoboranen) erfolgt über die B-N-Kupplung von Chlorboranen und Silylamin-Vorstufen durch ClSiMe 3 -Eliminierung. [10] Die Gruppe um Helten verwendete diese Methodik für die Synthese der ersten wohldefinierten Oligo(iminoborane) (V), welche durch Polykondensation einer 1,3-Bis(trimethylsilyl)-1,3,2-diazaborolidin-Vorstufe mit Dichlor(organo)boranen (Schema 1 a) erfolgt. [11] Unsere Gruppe hat ebenfalls über eine Kupplung von zwei Cl 2 BN-(SiMe 3 ) 2 -Molekülen an [(C 5 H 5 )Ru(CO) 2 ]Na unter Abspaltung von NaCl und ClSiMe 3 berichtet, wodurch der (N-Aminoboryl)aminoboryl-Komplex VI erhalten wurde (Schema 1 b).…”

“…[a]: = +26.9 (c = 0.423 in CHC13), in 57 % yield. Careful chromatographic separation of the reaction product on A1203 yielded, in addition to (2) and 24 % dechlorinated starting material, 3.5 7; of the desired AzI(N)-unsaturated compound Disilazanes are cleaved at the Si-N bond by boron halides [2, 31, and are transaminated by aminoboranes [4]; both reactions lead to compounds containing the )B-NH-Si< grouping.…”
