The reaction of C60 fullerene with carboalkoxycarbenoids generated by Rh2(OAc)4-catalyzed decomposition of α-diazoester precursors is reported. This reaction is the first example of a transition metal catalyzed carbenoid reaction with fullerene and represents a significative improvement in terms of reaction conditions, selectivity of the products obtained, and yields over previously reported methods.
