چکیده

A cyclotriveratrylene-based molecular cage forms hemicarceplexes that significantly increase the solubility of commercially available Sc3N@C80 in CDCl3. When incarcerated within the molecular cage, the two structural isomers of this metallofullerene, Sc3N@D5h-C80 and Sc3N@Ih-C80, displayed characteristic signals in both (1)H and (13)C NMR spectra, allowing direct identification of each isomer without the need to enrich the sample with (13)C atoms.

An efficient method to separate Sc3N@C80 Ih and D5h isomers and Sc3N@C78 by selective oxidation with acetylferrocenium [Fe(COCH3C5H4)Cp]+.

Based on the different oxidation potentials of endohedral fullerenes Sc3N@C80 Ih and D5h and Sc3N@C78, an efficient and useful method that avoids HPLC has been developed for their separation. Selective chemical oxidation of the Sc3N@D5h-C80 isomer and Sc3N@C78 by using an acetylferrocenium salt [Fe(COCH3C5H4)Cp](+) followed by column chromatographic separation and reduction with CH3SNa resulted...

A crystalline anionic complex of scandium nitride endometallofullerene: experimental observation of single-bonded (Sc3N@Ih-C80−)2 dimers†

Reduction of scandium nitride clusterfullerene, Sc3N@Ih-C80, by sodium fluorenone ketyl in the presence of cryptand[2,2,2] allows the crystallization of the {cryptand[2,2,2](Na(+))}2(Sc3N@Ih-C80(-))2·2.5C6H4Cl2 (1) salt. The Sc3N@Ih-C80˙(-) radical anions are dimerized to form single-bonded (Sc3N@Ih-C80(-))2 dimers.

Sc3CH@C80: selective 13C enrichment of the central carbon atom†

Sc3CH@C80 is synthesized and characterized by (1)H, (13)C, and (45)Sc NMR. A large negative chemical shift of the proton, -11.73 ppm in the Ih and -8.79 ppm in the D5h C80 cage isomers, is found. (13)C satellites in the (1)H NMR spectrum enabled indirect determination of the (13)C chemical shift for the central carbon at 173 ± 1 ppm. Intensity of the satellites allowed determination of the (13)...

Reactivity differences of Sc3N@C(2n) (2n = 68 and 80). Synthesis of the first methanofullerene derivatives of Sc3N@D(5h)-C80.

Using a purification method introduced earlier based on redox properties it was possible to isolate Sc3N@I(h)-C80 and Sc3N@D(3h)-C78 and a mixture of Sc3N@D(5h)-C80 and Sc3N@D3-C68. Taking advantage of their chemical reactivity differences, Sc3N@D(5h)-C80 was isolated from Sc3N@D3-C68 followed by further functionalization, giving rise to five new methano-derivatives of Sc3N@D(5h)-C80.

Scandium carbide/cyanide alloyed cluster inside fullerene cage: synthesis and structural studies of Sc3(μ3-C2)(μ3-CN)@Ih-C80.

A new Sc3(C2)(CN)@Ih-C80 metallofullerene encaging a scandium carbide/cyanide alloyed cluster was prepared and investigated. Sc3(C2)(CN)@Ih-C80 was synthesized by the arc-discharging method and isolated by HPLC. Its experimental (13)C NMR spectrum with two signals clearly confirms an icosahedral C80 cage, and theoretically calculated (13)C NMR peaks agree well with the experimental results. Fur...
