We report a convenient and simple solution-phase electron-transfer reaction Of C-60 with zinc and alpha-bromoacetonitrile, alpha-bromo acetate esters, allyl bromide, benzyl bromide and a-bromo ketones in DDIF, with which different types of monoalkylated C-60 derivatives can be prepared. When this method is employed with C-70, 2-carbomethoxymethyl-1,2-dihydro[70]fullerene (isomer 5a) is produced as one of the two 1,2-monoalkylated C-70 isomers, together with the first 5,6-monoalkylated C-70 derivative.
