[摘要]：Tris(9',10'-dimethyl[9,10]ethanoanthracene[11',12':1,9;11",12":16,17;11"',12"':30,31])[5,6]fullerene C-60, the orthogonal (e,e,e)-tris-adduct of C-60 and 9,10-dimethylanthracene, was obtaines from [4+2]-cycloaddition (Diels-Alder reaction) at room temperature. The thermally unstable orange red (e,e,e)-tris-adduct was purified by chromatography and was isolated in the form of red monoclinic crystals. Its C-3-symmetric addition pattern was established spectroscopically. Its sturucture could be further investigated by single crystal X-ray diffraction. The (e,e,e)-tris-adduct of C-60 and 9,10-dimethylanthracene has earlier been suggested as intermediate and reversibly formed critical component in 'template directed' addtion reaction of C-60. This previously elusive compund has now been isolated and strucutrally characterized. |
