  名称：

  SYNTHESES OF 8-(1,2,3,4-TETRACHLOROFULVEN-6-YL)HEPTAFULVENE AND 8-(9-FLUORENYLIDENE)METHYLHEPTAFULVENE

  摘要：

  Treatment of [2-(2,3,4,5-tetrachloro-1,3-cyclopentadienyl)vinyl]tropylium fluoroborate 9 with bases gave 8-(1,2,3,4-tetrachlorofulven-6-yl)heptafulvene 4. In similar way 8-(9-fluorenylidene)methyl heptafulvene 5 was also prepared. 4 is more polar than 5 is, but is less stable. Both 4 and 5 easily gave [8+2] cycloadducts with tetracyanoethylene.
