Beiträge zur Chemie des Bors, XLVI. Zur Chemie cyclischer und käfigförmiger Hydrazinoborane

Abstract

Der Strukturunterschied zwischen den dimeren und tetrameren Hydrazinoboranen (RBNR'NR')), (Sechsring-bzw. Kafigsystem) manifestiert sich im unterschiedlichen chemischen Verhalten: Je nach Art der Substituenten R' und R ' fdhrt die Reaktion zwischen (RBNR"R')z (1) und HCI zur Addition von 2 Molaquivv. HCl (2) bzw. zur Spaltung der BN-Bindungen.

Synthesis and Structure of Mes*AlN(Ph)Al(Mes*)N(Ph)NPh: A Formal Aluminum−Nitrogen Analog of the Cyclopentadienide Ion

“…In contrast to these compounds, formal main group III−V analogs of the aromatic cyclopentadienide anion are much less well studied. A few boron−nitrogen compounds which contain the B 2 N 3 ring system have been reported, but no heavier congeners with M 2 N 3 (M = Al, Ga, In) have been characterized. In this paper, the synthesis and characterization of the first such species, Mes*AlN(Ph)Al(Mes*)N(Ph)NPh ( 1 ), are now described.…”

Synthesis, Structure, and Reactivity of Diazene Adducts: Isolation of iso‐Diazene Stabilized as a Borane Adduct

“…[59] Additionally, transition-metal complexes exist of the type [M]ÀN(R)=NÀR and [M]À N=NÀR with aryl-substituted diazene and diazenido ligands, respectively. [60][61][62][63][64][65][66] Finally, hydrazinoboranes (also known as boryl hydrazines) represent a well-established class of compounds, [67][68][69][70][71] however, to the best of our knowledge no pentafluorophenyl-substituted hydrazine derivative is known to date. For both hydrazinoboranes 10 and 11 the 19 F NMR spectra showed nine resonances (Table 1, see the Supporting Information), in accordance with hindered rotation about the NÀB bond.…”
