An open‐cage C 60 derivative 9 with anilino, hemiketal, and lactone moieties on the edge of the opening was prepared through a fullerene‐mixed peroxide procedure. Key steps include decarbonylation, intramolecular Friedel–Crafts reaction and oxetane ring opening rearrangement. The open‐cage compound 9 readily reacts with various metal salts. A nickel complex was obtained by treating 9 with NiCl 2 at r.t. followed by purification on a silica gel column. Single‐crystal X‐ray diffraction analysis showed that the nickel ion is coordinated to two ligands with an octahedral geometry.
