摘要

The efficient preparation of monoadducts of [60]fullerene and seven anthracenes(anthracene,1-methylan-thracene,2-methylanthracene,9-meth-ylanthracene,9,10-dimethylanthracene,2,3,6,7-tetramethylanthracene,and 2,6-di-tert-butylanthracene)by cycloaddi-tion in solution is described.The Seven mono-adducts of [60]fullerene and the anthracenes were characterized spectro-scopically and were obtained in good yields as crystalline solids.The mono-adducts of [60]fullerene and anthracene,1-methylanthracene,2-methylanthra-cene and 9,10-dimethylanthracene crys-tallized directly from the reaction mix-ture.The thermolytic decomposition at 180 deg C of the crystalline monoadducts of [60]fullerene and anthracene,1-methy1-anthracene,9-methylanthracene and 9,10-dimethylanthracene all gave rise to the specific formation of a roughly 1:1 mixture of [60] fullerene and the corresponding antipodal bisadducts ("trans-1"-bisadducts)of [60]fullerene and the .In contras,the crystalline monoadducts of [60]fullerene and the anthracene derivatives 2-meth-ylanthracene,2,3,6,7-tetramethylanthra-cene and 2.6-di tert butylanthracene all decomposed to [60]fullerene and an thracenes(without detectable formation of bisadducts)upon heating in the solid state to temperatures of 180 to 240 deg C.The formation of the antipodal bisad-ducts from thermolkytic decomposition of crystalline samples of the monoad-ducts was rationalized by topochemical control.
