Deoxygenation of Some α-Dicarbonyl Compounds by Tris(diethylamino)phosphine in the Presence of Fullerene C60

The reactions of such cyclic α-diketones as acenaphthenequinone, aceanthrenequinone, and N-alkylisatins, with hexaethyltriaminophosphine in the presence of the fullerene C(60), lead to the formation of methanofullerene derivatives under mild conditions. This process proceeds via deoxygenation of the dicarbonyl compound by the P(III) derivative and is likely to involve the intermediate formation of α-ketocarbenes. The structure of some methanofullerenes has been confirmed by NMR and XRD. The electrochemical behavior of the methanofullerenes was also investigated.

Proton-acceptor properties of azahomofullerene and fullerenoaziridine containing a cyanuric acid fragment

Abstract13C and 1H NMR and UV spectral studies on 1,3-diallyl-5-[4-(azahomo[60]fullereno)butyl]hexahydro-1,3,5-triazine-2,4,6-trione ([5,6]-open isomer) and 1,3-diallyl-5-[4-(aziridino[60]fullereno)butyl]hexahydro-1,3,5-triazine-2,4,6-trione ([6,6]-closed isomer), as well as quantum-chemical calculations, showed that only the latter possesses weakly basic properties.

Phosphorylated azahomo[60]fullerene: synthesis and electrochemical properties

A reaction of [60]fullerene with O,O-dibutyl azidophosphate affords a first representative of phosphorylated azahomo[60]fullerenes, which is easier to reduce electrochemically than the starting C60.

Multi-Component Reactions in Supramolecular Chemistry and Material Science

Multi-component reactions of building blocks with more than one MCR-reactive group will give rise to oligomeric MCR products. The proper choice of at least two bifunctional building blocks will give either a polymeric or a cyclic product. Apart from polymerization, repetitive or consecutive Ugi reactions have been used to produce linear MCR-heterooligomers with such building blocks.

The Formation of Ion-Radical Salts in the Reaction of Fullerene C60 with Phosphorus (III) Amides

It was shown by ESR, 32P NMR and UV spectroscopy that fullerene forms ion-radical salts with hexamethyl- and hexaethyltriaminophosphines.

Synthesis and electrochemical properties of individual isomers of isocyanurate-substituted bis-organodiazadihomofullerenes

The reactions of fullerene C60 with isocyanurate-substituted azides afforded individual regioisomers of bis-adducts. The structures of the regioisomers depend on the structure of the organic fragment in azide and are determined primarily by the bulkiness of this fragment.

Synthesis and electrochemical properties of fullerene-containing C60-acceptor dyads with fluoronitrobenzene and fluoroquinoxaline moieties as substituents

Reactions of fullerene C60 with 4-azido-3-fluoro-1-nitrobenzene and 7-azido-6-fluoroquinoxaline afforded earlier unknown cycloadducts (C60-acceptor dyads), in which the electron affinities of the fullerene spheres are comparable with the affinity of nonmodified C60.
