The present invention provides Sumanene, its derivative and a method for manufacturing Sumanene and its derivative. As shown by a below-described scheme, benzotris(norbornadiene) (a below formula (87)) is firstly synthesized from norbornadiene (a below formula (86)). Then, the compound is subjected to a metathesis reaction so as to synthesize hexahydrosumanene (a below formula (88)), and it is dehydrogenized so as to obtain Sumanene (a below formula (84)). Thereby, Sumanene can be mass-synthesized under a moderate condition. In addition, a compound with a structure where a benzyl position of Sumanene is substituted by a N atom or an O atom can be obtained similarly, and various derivatives also can be obtained by further chemical modification of the compound. Sumanene and its derivative are suitable for electronic materials, synthesis raw materials for various kinds of fullerenes and heterofullerenes, and the like.

本发明提供了苏曼烯(Sumanene)、其衍生物以及制备苏曼烯及其衍生物的方法。如下所述的方案所示,首先从去氢莰烯(norbornadiene)(下式(86))合成苯三氮莰烯(benzotris(norbornadiene))(下式(87))。然后,将该化合物经过交换反应,合成六氢苏曼烯(hexahydrosumanene)(下式(88)),并经脱氢处理,从而得到苏曼烯(下式(84))。因此,在适中条件下可以大规模合成苏曼烯。此外,类似地,可以获得一个结构中苏曼烯的苄位被N原子或O原子取代的化合物,并且通过对该化合物的进一步化学修饰也可以获得各种衍生物。苏曼烯及其衍生物适用于电子材料、各种富勒烯和杂原子富勒烯的合成原料等。反应条件如下:a)BuLi、t-BuOK、BrCH2CH2Br、THF、-78°C至-45°C,随后CuI,室温;b)(PCy3)2RuCl2═CHPh催化剂量、CH2═CH2、甲苯、0°C至80°C;c)DDQ、甲苯、110°C。
