In this paper we report the electrochemical behavior of the simplest hydrocarbon derivative, C[sub 60]H[sub 2]. Samples of C[sub 60]H[sub 2] were prepared by zinc/acid reduction and purified by gel permeation chromatography in toluene. The identity of each sample was confirmed by negative ion FABS mass spectrometry, and the purity was determined to be 90% by C[sub 18] reversed-phase HPLC. In many respects, the electrochemical behavior of C[sub 60]H[sub 2] is very similar to that of the parent fullerene, with C[sub 60]H[sub 2] being only slightly more difficult to reduce than C[sub 60] itself. For example, in benzonitrile 0.1 M tetrabutylammonium hexafluorophosphate, three reversible reductions are observed (at sweep rates 1000 mV/s), and the half-wave potential for each of these processes is 120-170 mV more negative than that for the corresponding C[sub 60] reduction. Similar results were obtained in CH[sub 2]Cl[sub 2] and in toluene CH[sub 3]CN (80/20). An additional fourth reversible reduction, at -2.36 V vs Fc[sup +]Fc, was noted in the case of toluene CH[sub 3]CN; this couple is tentatively assigned to C[sub 60]H[sub 2][sup 3[minus] 4[minus]]. 18 refs., 3 figs., 1 tab.
