Cycloaddition of Functionalized Nitrile Oxides and Fulminic Acid to [60]Fullerene

Abstract Cycloaddition of nitrile oxides to [60]fullerene led to [60]fullereno[1,2‐d]isoxazole derivatives 1b–d. [60]Fullereno[1,2‐d]isoxazole (1a) is the corresponding cycloadduct with fulminic acid. X‐ray structure analyses of compound 1b and 1e were determined.
