At long last , the elusive thermodynamically most stable isomer of C 71 H 2 (see structure) has been synthesized through the addition of CH 2 across an equatorial bond of C 70 : a site at which such a reaction is not kinetically favorable. Theoretical studies revealed that the pyrogenic synthetic method used enables reactants to overcome the higher activation barrier to equatorial addition.
