title: Regioselective [2 + 2] cycloaddition of a fullerene dimer with an alkyne triggered by thermolysis of an interfullerene C-C bond.
abstract: Heating of a singly bonded fullerene dimer in the presence of an alkyne forms a cyclobutene structure on only one of the two fullerene moieties, through a stereo- and regioselective [2 + 2] cycloaddition. Experimental and theoretical data suggest that the reaction is triggered by cleavage of the interfullerene C-C bond and formation of a monomeric fullerene radical.
