摘要： <正>研究了脱氢枞胺兮子中的芳环结构与C60Friedel-Crafts反应产物。将C60、脱氨枞胺及无水AlCl4在氟苯溶利中，在避光条件下于130℃反应3d。反应产物经过柱层析分离，用IR、1HnmR、13CnmR、ESI-MS等分析方法对反应主要产物进行结构测定，发现并未生成预期的Friedel-Crafts反应产物。却得到C60，与脱氢枞胺的胺加成反应产物。主产物为氨基与碳球相连的单加成结构。

Abstract: A necessary condition that all cyclic S -posers are flat was given. The condition is not sufficient which is illustrated by an example. The results on S - acts can be also obtained as applications of the results of this paper. The question raised by Bulman-Fleming et al was answered partly.
