摘要：

Thermal dehydrocyclization as well as isomerization reactions of 9,9'-bi-9H-fluorenylidene (2) have been investigated at temperatures above 700 degrees C in the gas phase resulting in benz[e]indeno(1,2,3-hi)acephenanthrylene (3) and dibenzo[g,p]chrysene (4), respectively. If 4 is catalytically converted, benz[g]indeno[1,2,3,4-mnop]chrysene (5) is formed in resonable yields by dehydrocyclization. Separate pyrolysis runs of 3 and 5 at temperatures above 900 degrees C give finally diindeno[1,2,3,4-defg;1',2',3',4'-mnop]chrysene (1), a bowl-shaped subunit of buckminsterfullerenes, besides other polycyclic aromatic hydrocarbons.
