NH Bond Activation of Hydrazine Using Cyclic (alkyl)(amino)carbenes and Boranes

ChemistryEurope
We report the reactivity of cyclic (alkyl)(amino)carbenes (cAACs) with hydrazine derivatives. EtcAAC (1) activates the NH bond of phenyl‐substituted hydrazine derivatives, while analogous reactions with unsubstituted hydrazine (N2H4) were not tractable.

From betaines to anionic N-heterocyclic carbenes. Borane, gold, rhodium, and nickel complexes starting from an imidazoliumphenolate and its carbene tautomer

Beilstein Journal of Organic Chemistry, 2016
The mesomeric betaine imidazolium-1-ylphenolate forms a borane adduct with tris(pentafluorophenyl)borane by coordination with the phenolate oxygen, whereas its NHC tautomer 1-(2-phenol)imidazol-2-ylidene reacts with (triphenylphosphine)gold(I) chloride ...

Discovery of bicyclic borane molecule B14H26

Communications Chemistry
The discovery of fullerene following the synthesis of graphene marked a paradigm shift in chemistry. Here, we report the discovery of biycycloborane, arising from the synthesis of borophane (hydrogen boride).
