摘要：

Repeated treatment of the C-2v-symmetrical C-60 pentakis-adducts la,b with diazomethane provided with high regioselectively the novel heptakis- 5 and octakis-adducts 4a,b via hexakis-adducts 3a,b; an orbital symmetry-controlled reaction mechanism for the thermal dinitrogen extrusion from the pyrazoline intermediates in the addition of diazomethane to fullerenes is proposed.
