Deacylations of substituted 9-acetyl-, 9-propionyl-, 9-benzoyl-fluorene, and 9-fluorenyl 9-methyl-9-fluorenyl ketones were studied; the reactivity of deacylation was enhanced by the substitution of the 9-hydrogen atom on 9-acetylfluorene. The reaction of 9-acetylfluorene with ethyl nitrate afforded 9-aci-nitrofluorene.
