Bor‐Stickstoff‐Verbindungen, X. Einige neue Aminoborane

Abstract: Aminoborane, R2N-BR2, sind isoelektronisch mit Olefinen und schon E. WIBERG 2) berichtete iiber weitgehende Analogien physikalisch-chemischer Konstanten beider Verbindungsklassen. Kurzlich wurde erstmals iiber die Darstellung unsymmetrisch substituierter Aminoborane berichtet und dabei die Vermutung ausgesprochen, daI3 bei Aminoboranen cis-transIsomerie moglich sei3). Voraussetzung hierfiir ist eine weitgehende Beteiligung des freien Stickstoff-Elektronenpaan an der B -N-Bmdung: Tatsachlich lieI3 sich eine Beh… Show more

“…If the reaction is performed with BCI 3 one obtains the 1,5-diaza-2,6-dibora-bicyclo- Surprisingly compound 8 (Y = Et 2 N) is obtained in the reaction of D with chlorobis(diethylamino)borane together with B(NEt 2 ) 3 . The corresponding diborylated ketazine was not formed even with an excess of (Et 2 N) 2 BCI.…”
