Cymantrenyl and styryl derivatives of 1-methyl[60]fullereno[c]pyrrolidine: Synthesis and electrochemical behavior

New cymantrenyl derivatives of 1-methyl[60]fullereno[c]pyrrolidine were obtained. According to electrochemical data, the cymantrenyl and phenyl fragments show close electron-donating effects in the presence of the strong acceptor fullerene.
