1,2-benzofulvene (6a) and 1,2,3,4-dibenzofulvene (7a) as well as the corresponding 6-methyl- and 6-phenyl-derivatives are prepared by reaction of sodium indenide and sodium fluorenide with acetoxychloromethanes, followed by elimination of acetic acid with KOC(CH3)3. The over-all yields are comparable with the results of the fulvene series.
