Metal-Induced Tuning of Fullerene Reactivity: Application to Nucleophile Addition. [PDF]

Chemphyschem
A textbook case of how encapsulating an atom in a carbon cage can tune assembly reactivity based on partial charge distribution–exemplified by the classic nucleophilic attack. Endohedral metallofullerenes (EMFs) are a unique class of hybrid molecules formed by encapsulating metal atoms within carbon cages (fullerenes), giving rise to distinctive ...

Inverse Electron Demand Diels-Alder Reaction on M₃N@C₈₀ (M=Lu, Sc): Reactivity and Reversibility Enable Chemical Separation of Metallofullerenes. [PDF]

Angew Chem Int Ed Engl
An inverse electron demand Diels–Alder (IEDDA) reaction on M3N@Ih‐C80 (M=Lu, Sc) has been utilized to yield [5,6]‐closed [4+2] cycloadducts that were fully characterized (HPLC, MS, UV/Vis and NMR spectroscopy, X‐ray crystallography, and DFT calculations).

Capturing Unstable Metallofullerenes [PDF]

Inorganics
Metallofullerenes are interesting molecules with unique structures and physicochemical properties. After they are formed in the arc-discharge process, they are first buried in the carbon soot, which requires solvent extraction to fish them out, normally ...

DFT Study of NO and NO₂ Adsorption onto Endohedral Metallofullerenols (M@C₆₀(OH)_n; M = Li, Ca, Y; n = 0, 6, 12, 18, 24) [PDF]

Molecules
Nitrites and nitrates are admitted into the body through the consumption of various foods, primarily cured meat products. These nitrites and nitrates are precursors of reactive nitrogen species NO and NO2, which, in excess, promote nitrosative stress ...

DFT Calculations of Structure and IR Spectra of Gd₂@C₈₂ Endofullerenes [PDF]

Molecules
Dimetallofullerenes are obtained in synthesis in parallel to monometallofullerenes, but they are less studied because their yields are considerably lower. In this work, DFT modeling of Gd2@C82 endohedral metallofullerene (EMF) has been performed. A total

Controlling the reactivity of La@C82 by reduction: reaction of the La@C82 anion with alkyl halide with high regioselectivity [PDF]

Beilstein Journal of Organic Chemistry, 2023
Endohedral metallofullerenes have excellent redox properties, which can be used to vary their reactivity to certain classes of molecules, such as alkyl halides. In this study, the thermal reaction of the La@C2v-C82 anion with benzyl bromide derivatives 1

Actinide-lanthanide single electron metal-metal bond formed in mixed-valence di-metallofullerenes [PDF]

Nature Communications, 2023
Understanding metal-metal bonding involving f-block elements has been a challenging goal in chemistry. Here we report a series of mixed-valence di-metallofullerenes, ThDy@C2n (2n = 72, 76, 78, and 80) and ThY@C2n (2n = 72 and 78), which feature single ...
