Abstract

A logical precursor of macrocycle C₆₀ H₆ , cyclophane C₆₀ H₆ (CO)₁₂ (1) represents a building block in a possible total synthesis of C₆₀ . In Fourier transform ion cyclotron resonance laser desorption mass spectroscopic experiments in the negative-ion mode, 1 fragments to C₆₀ H₆ (2) under successive loss of CO. Further loss of six H atoms and rearrangement gives C₆₀ ions with a fullerenic structure.
