Synthesis of 1,2-(2,3-dihydro-1H-azirino)-[60]fullerene, the parent fulleroaziridine

Computational synthesis of C60 cyano- and azopolyderivatives

“…Obviously, a high I h grade of continuous symmetry implies that symmetric patterns related not only to I h itself but to its subgroups might be expected. From this viewpoint, attributing the high-symmetry pattern of 13 C NMR spectra of these species to the C 2v group [14] does not seem strange and inconsistent with computational predictions. The continuous symmetry contribution of C 3v to the molecular structure of 9NH is 98.7%.…”

“…1 composition of the addend, particularly in the case of polyadditions. In the present work, we will consider a particular family of azoderivatives of C 60 fullerene [14] taken from among the large class of fulleroaziridines.…”

“…So far there has only been one report [14] on the production and characterization of the first member of this series, which assigned its symmetry to the C 2v point group. This substance (denoted molecule II) was discussed in [11] in regards to the continuous symmetry of fullerene derivatives and their electronic spectra.…”

Cluster Modified Fullerenes

“…11.2.1 "Fulleroids": Bridged Adducts with Open Transannular Bonds transannular [5,6]-bond in all parent fulleroids 1 [5], 2 [6] and 3 [7] is open and the 60 π-electron system of the fullerene core remains intact. Ring opening from a hypothetical precursor adduct with a closed transannular [5,6]-bond can formally be regarded as a retro-electrocyclic reaction (Scheme 11.1).…”

“…Whereas in 4 and 5 two [5,6]-bonds are open, the bisazafulleroids 6 represents the first examples of bridged [6,6]-adducts (cis-1 addition pattern) with open transannular bonds. In this case three [5,6]-double bonds have to be introduced.…”
