Cycloaddition of nitrile oxides to [60]fullerene

Chemical Communications, 1997
The addition of nitrile oxides to [60]fullerene is examined and it is found that the reaction products regenerate [60]fullerene under relatively mild conditions; the result is potentially useful for better control of fullerene functionalization.

Rearrangements of Aromatic Nitrile Oxides and Nitrile Ylides: Potential Ring Expansion to Cycloheptatetraene Derivatives Mimicking Arylcarbenes

Chemistry - A European Journal, 2020
Nitrile imines, nitrile oxides and nitrile ylides are widely used in 1,3-dipolar cycloaddition reactions. They also undergo thermal and photochemical rearrangements to carbodiimides, isocyanates, and ketenimines, respectively.
