Voltammetric characterization of C60(PhX)2 (X = H, Br) and digital simulation of their electrochemically-induced reactivity.

The electrochemistry of two new 1,7-diaryl C(60) phenylated derivatives is explored in THF at various temperatures (from 25 to -90 degrees C). While at room temperature their voltammetric response is that typically shown by fairly stable species, when the temperature drops a very high electrochemically induced reactivity is evidenced. The investigation of the voltammetric patterns supported by an extensive use of digital simulation techniques finally led to the formulation of a reaction mechanism that includes electrochemically-induced migration of the phenyl groups as a possible explanation of the observed behavior.
