Summary
Nitrogen endohedral fullerene epoxide (N@C60O) was synthesized and studied. The nitrogen radical
Area of Science:
- Endohedral fullerenes
- Nitrogen-doped fullerenes
- Radical chemistry
Background:
- Endohedral fullerenes encapsulate atoms or molecules within a fullerene cage.
- Fullerene epoxides are reactive intermediates in fullerene chemistry.
- Nitrogen radicals in endohedral fullerenes are of interest for their unique electronic and magnetic properties.
Purpose of the Study:
- To synthesize and characterize the nitrogen-doped endohedral fullerene epoxide (N@C60O).
- To investigate the magnetic properties and radical behavior of N@C60O.
- To elucidate the reaction mechanism of C60O with C60 in the solid state.
Main Methods:
- Synthesis of N@C60O.
- Isolation using High Performance Liquid Chromatography (HPLC).
- Characterization by Electron Spin Resonance (ESR) spectroscopy.
Main Results:
- N@C60O was successfully synthesized and isolated.
- ESR spectroscopy confirmed the presence of a nitrogen radical with predominantly axial symmetry (D=6.6 MHz, E=0.5 MHz at 77 K).
- Photo- and thermal-induced silencing of the nitrogen radical were observed, with a new spin signal appearing at 100°C.
Conclusions:
- The observed silencing of the nitrogen radical suggests coupling with a radical formed from epoxide ring opening.
- The reaction of C60O with C60 in the solid state likely proceeds through a radical intermediate.
- This study provides insights into the reactivity and radical mechanisms involving endohedral fullerene epoxides.

02:17Synthesis and Decomposition Reactions
Synthesis and decomposition are two types of redox reactions. Synthesis means to make something, whereas decomposition means to break something. The reactions are accompanied by chemical and energy changes.
01:26Synthesis of α-Substituted Carbonyl Compounds: The Stork Enamine Reaction
α-Substituted ketones or aldehydes can be synthesized from enamines by the Stork enamine reaction, named after its pioneer Gilbert Stork. Enamines are useful synthetic intermediates where the lone pair on nitrogen is in conjugation with the C=C bond. They resemble enolate ions, as the resonance forms of both species have a nucleophilic α carbon.
01:16Cycloaddition Reactions: Overview
Cycloadditions are one of the most valuable and effective synthesis routes to form cyclic compounds. These are concerted pericyclic reactions between two unsaturated compounds resulting in a cyclic product with two new σ bonds formed at the expense of π bonds. The [4 + 2] cycloaddition, known as the Diels–Alder reaction, is the most common. The other example is a [2 + 2] cycloaddition.
01:32Aldehydes and Ketones with HCN: Cyanohydrin Formation Overview
Cyanohydrins are compounds that contain –CN and –OH groups on the same carbon atom. They are formed by the nucleophilic addition of the cyanide ions to the carbonyl group. Cyanide ions are highly basic and nucleophilic and can be generated from HCN under aqueous conditions. However, since HCN is a weak acid, the number of cyanide ions generated is very small. Hence, a small amount of base or KCN/NaCN is added to HCN to increase the concentration of the cyanide ions in the reaction mixture.
02:27Preparation of Alkynes: Alkylation Reaction
Introduction
Alkylation of terminal alkynes with primary alkyl halides in the presence of a strong base like sodium amide is one of the common methods for the synthesis of longer carbon-chain alkynes. For example, treatment of 1-propyne with sodium amide followed by reaction with ethyl bromide yields 2-pentyne.

01:26Thermal and Photochemical Electrocyclic Reactions: Overview
Electrocyclic reactions are reversible reactions. They involve an intramolecular cyclization or ring-opening of a conjugated polyene. Shown below are two examples of electrocyclic reactions. In the first reaction, the formation of the cyclic product is favored. In contrast, in the second reaction, ring-opening is favored due to the high ring strain associated with cyclobutene formation.
