[60]Fullerene is irradiated in the presence of the electron transfer sensitizer 9,10-dicyanoanthracene (DCA) under cosensitization with biphenyl. The generated radical cation C-60(.+) reacts with H-donors such as tert-butylmethyl ether, propionaldehyde and alcohols to give 1:1-adducts, the 1-substituted 1,2-dihydro[60]fullerenes.

A new general reaction for the preparation of isomerically pure hydroxyalkylated C(60) monoadducts, via the freeradical photochemical addition of alcohols to [60]fullerene, is described.

several fullerene derivatives have been studied. In general, NMTAD cycloadds to C60 and to its monoadducts with closed structures in a highly regioselective [2+2] fashion at a cis-1 [6,6] double bond. Cycloadditions to azafulleroids occur by a slightly different pathway and result in partially cluster-opened bis(adducts). 1,6-Methano[60]fulleroid, however, also undergoes a [2+2+2] cycloaddition in the
