    • 4 has a structure consisting of two fullerene cages directly connected forming a butane ring and two CH2 bridges in 1,4 position. The resulting fullerene dimer has two hexagons of the adjacent cages situated in a "face-to-face" manner; N. Dragoe et al., unpublished data

    • The synthesis was performed as described in reference 11. For the compounds 2, three samples were used: 2-1 the trans-2 bisadduct, 2-2 a mixture of trans-3 and trans-4 bisadducts, respectively and 2-3 the equatorial bisadduct. The notation is that proposed by Hirsch; Hirsch, A. The Chemistry of Fullerenes, G. Thieme Verlag, Stuttgart-New York, 1994

    • TG-MS was performed in inert atmosphere (Ne flow) with a Seiko TG/DTA6300 coupled with a GC HP5890 through a stainless steel coupling line of 0.25 mm diameter, 5 m length, kept at 300°C. The MS was Jeol AutoMass System II measuring every second in the range 10-900 amu. GC-MS was measured with a Double Shot pyroliser FrontierLab 2010D coupled with an AutoMass System II measuring every second in the range 8 to 350 amu.

    • Although no indices of cyclopropane decomposition has been found, in agreement with a reaction mechanism described in Scheme 1, the relative large amount of C60 in the reaction product (10 to 30 %) suggests that a cyclopropane decomposition reaction may occur either from the starting compounds of from the products.

    • The thermolysis was performed at 5K/min; at this heating rate the CO2 and aliphatic parts eliminations occur at 380 C and 540 C. The values of 415 and 620 C reffer to a heating rate of 20K/min, which was used in the TG-MS measurements.

    • The mixtures 1′, 2′, 3′ and 4′ are not totally soluble in CS2 or other solvents indicating the presence of molecules with higher molecular masses. This assumption is supported by the lowest solubility of 2′; bisadducts lead to cross-linked polymers which should be less soluble than the linear ones. 30 to 50% of the products 1′, 2′, 3′ and 4′ consist of insoluble material.
