Thermal cyclization of 7,10-diethynylfluoranthene (3) in the gas phase gives corannulene (2), the smallest bowl-shaped polycyclic hydrocarbon fragment of C60 with fullerene-like curvature. Bromocorannulene (10) and 1,6-dibromocorannulene (9) have also been obtained from flash pyrolysis of 7,10-bis(2,2-dibromovinyl)fluoranthene (8). Short, practical syntheses of several corannulene precursors from acenaphthenequinone
气相中 7,10-二乙炔基荧蒽 (3) 的热环化得到芴烯 (2),这是 C60 的最小碗状多环烃片段,具有类似富勒烯的曲率。溴化芴烯 (10) 和 1,6- 二溴化芴烯 (9) 也已从 7,10-双 (2,2-二溴乙烯基) 荧蒽 (8) 的快速热解中获得。描述了从苊醌合成几种苊烯前体的简短、实用的合成方法,这使得苊烯可以达到克级量。
