摘要：

The Diels-Alder reaction of o-quinodimethanes to buckminsterfullerene C-60 (1) affords thermally stable derivatives. 4-Carboxy-o-quinodimethane (4)was prepared in situ from 3,4-bis(bromomethyl)benzoic acid (3) and reacted with 1 to give the carboxy-substituted adduct mixture 5(n). Due to its decreased solubility, 5(rt) was used without further purification for transformations into the corresponding esters and amines. This was achieved by two different methods: (a) via the carboxylic acid chloride 6(n), whereby the alcohol/amine has to be used in excess, and (2) via the active ester 7(n = 1), which allows stoichiometric reactions with amines. All these derivatives are quite Soluble in commonly used organic solvents. This enabled us to separate and completly characterize the products.
