Addition of carbene to the equator of C70 to produce the most stable C71H2 isomer: 2aH-2(12)a-homo(C7o-D 5h(6))[5,6]fullerene

Abstract

(Figure Presented) At long last, the elusive thermodynamically most stable isomer of C71,H2 (see structure) has been synthesized through the addition of CH2 across an equatorial bond Of C 70: a site at which sucha 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. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
