SUMANENE AND PROCESS FOR PRODUCTION THEREOF

摘要

The invention provides sumanene and derivatives thereof and a process for the production of both. As represented by the scheme (1), benzotris- (norbornadiene) (87) is synthesized from norbornadiene (86) and then converted by metathesis into hexahydrosumanene (88) and the heaxahydrosumanene (88) is dehydrogenated into sumanene (84). Thus, sumanene can be mass-produced under mild conditions. Further, sumanene analogues wherein the carbon atoms at the benzylic positions are replaced by nitrogen (N) or oxygen (O) can be also similarly produced and various derivatives can be obtained by further chemical modification of such analogues. Sumanene and analogues and derivatives thereof are extremely useful as the raw material for the synthesis of electronic materials, various fullerenes, and heterofullerenes, and so on.
