[60] buckyminsterfullerene (C60) and its derivatives have inimitable efficacy and bioactivity in anti-virus effect, anti-tumour effect, enzymatic inhibition , DNA cleavage and photodynamic therapy for their particular structures . they have gradually become a hotspot of scientific research. While dehydro- -abietylamine, which has a steroid -like structure, and can be used as excellent insecticide, bactericide etc. is a kind of derivative of abietic acid. Therefore, supposed a new molecule which is synthesized from C60 and dehydroabietylamine, and it would be a valuable topic to study the bioactivity of this new molecule.In this paper, [1+2] cycloaddition between C60 and dehydro- -abietylamine was researched. In this reaction, nitrenes was added to C60 as a active intermediate. Protected by N2, Pb(OAc)4 were added into chlorobenzene, in which C60 and dehydroabietylamine had already dissolved . The admixture reacted at refluence temperature over 24 h, and was purified by gel column chromatogram when the reaction was finished. A [5,6]opencyclo-monoaddition derivative and a diaddition derivative ,which have not been report in any articles, were obtained . The structures of these derivatives were charactered by IR, 1H NMR,13C NMR and MS.Amino addition between C60 and dehydroabietylamine was also studied. In dark, dry AlCl3 was added into chlorobenzene, in which C60 and dehydroabietylamine had already dissolved. The admixture reacted at refluence temperature over 3 d, and was purified by gel column chromatogram when the reaction was finished. An amino addition derivatives and an oxygen-containing derivative, which are not reported in any articles now, were obtained. The structures were charactered by IR, 1H NMR, 13C NMR and MS.Moreover, parallel reactions both under thermal condition and under microwave condition were researched. Keeping the same temperature and proportion, the admixture was radiated by 500 W microwaves. The time of [1+2]cycloaddition was shorten from 24 h to 1.5 h , while the yield was raised from 42.8% to 59.9%. The time of amino addition was shorten from 3 d to 2.5 h, but the yield was raised from 38.1% to 61.6%. The result of this research shows that the speed of reaction between C60 and dehydroabietylamine could be rised extremely in microwave condition.
