Novel [60]fullerene–TTF cyclohexene fused polyadducts: unprecedented tri- and tetra-Diels–Alder adducts of dimethylidene[2H]tetrathiafulvalenes with C60☆

Abstract The title compounds, which are formed in very low yields by treating 2,3-bis(bromomethyl)tetrathiafulvalenes with naked iodide in the presence of C 60 , can be obtained in much higher yields by successive similar treatments of the major adducts produced at each step. The electrochemical properties of the unprecedented tri- and tetra-TTF/C 60 assemblies are also presented.
