T1  - New Avenues in the Reactivity of Borylene Complexes
T1  - Neue Wege in der Reaktivität von Borylenkomplexen
N2  - The thesis is mainly about the reactivities of borylene complexes. Including the investigation of the reaction of base stabilized terminal borylene with elemental chalcogens. On the other hand the are also the reactivity of borylene with bipyridine species is also studies. A C-H activation of the Cp2WH2 using borylene is also discovered. Finally the reaction of a borylene with Lewis acids such as GaCl3 and InBr3 is also studied.
N2  - Die Fragestellung der Arbeit zielte auf die Erforschung der Reaktivität von Borylenkomplexen (20, 22, 43, 50, 90, 104). Reaktionen von Übergangsmetallborylen-Komplexen wurden mit einer Reihe von verschiedenen Reagenzien untersucht, deren Produkte neuartige Bindungsmotive zeigten. Viele der Verbindungen wurden als erste Beispiele ihrer Art isoliert, mit teils sehr ungewöhnlichen strukturellen Eigenschaften. Durch spektroskopische und strukturelle Charakterisierungsmethoden wurden sowohl die Konstitution der Verbindungen bestätigt als auch ihre Bindungsverhältnisse aufgeklärt ...

T1  - 2,2′-Bipyridyl as a Redox-Active Borylene Abstraction Agent
JF  - Inorganic Chemistry
N2  - 2,2′-Bipyridyl is shown to spontaneously abstract a borylene fragment (R–B:) from various hypovalent boron compounds. This process is a redox reaction in which the bipyridine is reduced and becomes a dianionic substituent bound to boron through its two nitrogen atoms. Various transition metal–borylene complexes and diboranes, as a well as a diborene, take part in this reaction. In the latter case, our results show an intriguing example of the homolytic cleavage of a B═B double bond.
