T1  - Synthesis of Boron Analogues of Enamines via Hydroamination of a Boron-Boron Triple Bond
BT  - Dedicated to Professor Wolfgang Kaim on the occasion of his 70th birthday
JF  - Angewandte Chemie, International Edition
N2  - An N-heterocyclic-carbene-stabilized diboryne undergoes rapid, high-yielding and catalyst-free hydroamina- tion reactions with primary amines, yielding 1-amino-2-hydro- diborenes, which can be considered boron analogues of enamines. The electronics of the organic substituent at nitrogen influence the structure and further reactivity of the diborene product. With electron-rich anilines, a second hydroamination can occur at the diborene to generate 1,1-diamino-2,2-dihy- drodiboranes. With isopropylamine, the electronic influence of the alkyl substituent upon the diborene leads to an unprece- dented boron-mediated intramolecular N-dearylation reaction of an N-heterocyclic carbene unit.

T1  - Lewisbasenstabilisierte Bor-Bor-Mehrfachbindungssysteme - Darstellung und Reaktivitätsstudien
T1  - Lewis base stabilized boron-boron multiple binding systems - Synthesis and reactivity
N2  - Diese Dissertation befasst sich mit der Darstellung und Reaktivität von Lewisbasenstabilisierten Bor-Bor-Mehrfachbindungssystemen.
Besonderes Augenmerk lag hierbei auf der Aktivierung von Element-Wasserstoff-Bindungen von Boranen, Aminen, Silanen und Phosphanen durch NHC-stabilisierte Diborine. Des Weiteren wurde die Aktivierung von Bor-Bor-, sowie Phosphor-Phosphor-Einfachbindungen untersucht. Zusätzlich wurde die Reaktivität gegenüber Carbenen und aromatischen Stickstoffbasen näher beleuchtet.
N2  - This dissertation deals with the representation and reactivity of Lewis base-stabilized boron-boron multiple bond systems.
Special attention was paid to the activation of element-hydrogen bonds of boranes, amines, silanes and phosphanes by NHC-stabilized diborins. Furthermore, the activation of boron-boron and phosphorus-phosphorus single bonds was investigated. In addition, the reactivity towards carbenes and aromatic nitrogen bases was investigated.
