By FAB-MS and 13C NMR spectroscopy the structures of three new imino[60]fullerenes have been established: two monoadducts 5 (σ-azaridinefullerene) and 7 (π-azafullaroid) and one bisadduct (π-bisazafullaroid) 8.

Iron-doped multi-walled carbon nanotubes (Fe/MWCNTs) is an efficient, ecofriendly and reusable heterogeneous nanocatalyst for the one-pot synthesis of heterocyclic compounds including bis-spiro piperidines, piperidines, dihydro-2-oxopyrroles, pyrazoles and diazepines at room temperature with good to excellent yields. The heterogeneous nanocatalyst was fully characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), inductively coupled plasma (ICP) and FT-IR analysis. Also, the structures of all prepared compounds were characterized by 1H NMR, 13C NMR, FT-IR, mass spectrometry (MS) and elemental analysis. The major advantages of these protocols are mild and green reaction conditions, short reaction times, clean reaction, operational simplicity, easy purification and good to excellent yields with the reusable heterogeneous nanocatalyst. The catalyst was ten recycled without significant loss of activity.
REACTION OF DIAZOLE ANIONS WITH HEXAFLUOROBENZENE: AN UNEXPECTEDLY FACILE ENTRY INTO HEXA(DIAZOL-1-YL)-BENZENES
Henrie, Robert N.,Yeager, Walter H.
, p. 415 - 426 (2007/10/02)
Diazole anions react with hexafluorobenzene to give hexa(diazol-1-yl)benzenes in excellent yield, even with unfavorable reaction stoichiometries.In contrast, pyrrole anions predominantly or exclusively 1,4-disubstituted products.This novel hexasubstitution reaction is discussed in terms of an SRN1 mechanism.
