Abstract

A logical precursor of macrocycle C<sub>60</sub> H<sub>6</sub> , cyclophane C<sub>60</sub> H<sub>6</sub> (CO)<sub>12</sub> (1) represents a building block in a possible total synthesis of C<sub>60</sub> . In Fourier transform ion cyclotron resonance laser desorption mass spectroscopic experiments in the negative-ion mode, 1 fragments to C<sub>60</sub> H<sub>6</sub> (2) under successive loss of CO. Further loss of six H atoms and rearrangement gives C<sub>60</sub> ions with a fullerenic structure.
