The [2+2] cycloaddition of 3-alkoxycoumarins with C60 proceeded stereoselectively under photoirradiation conditions to produce a new class of fullerene fused oligocyclic cyclobutane products. This reaction seems to progress via radical ion pair intermediates that arise from the SET processing of 3-alkoxycoumarins with the excited form of C60.
3-烷氧基香豆素与 C60 的 [2+2] 环加成在光照射条件下立体选择性地进行,以产生一类新的富勒烯稠合低聚环丁烷产品。该反应似乎通过自由基离子对中间体进行,这些中间体由 3-烷氧基香豆素与 C60 的激发形式的 SET 加工产生。
