摘要：
It was established by ESR that trimethylaminoboryl radicals formed by UV irradiation of BH(3)NMe(3) in the presence of di-tert-butyl peroxide in saturated benzene solutions of fullerene C-60, add to fullerenes to give C-.(60)-BH(2)NMe(3) spin-adducts. The latter undergo dimerization with a rate constant of ca. 2.5.10(6) L mol(-1) s(-1). A more prolonged photolysis of excess BH(3)NMe(3) in a benzene solution of C-60 results in multiple addition of the trimethylaminoboryl radicals to the fullerene to give stable radicals C-.(60)[BH(2)NMe(3)](n).
