Abstract: 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. Condition of the Reaction a) BuLi, t-BuOK, BrCH2CH2Br, THF, ?78° C. to ?45° C.
