Abstract

1, 2-Cyclopentenofluorene, 3'-methyl-1, 2-cyclopentadienofluorene and 3'-methyl-1, 2- cyclopentenofluorene have been prepared from fluorene-1-aldehyde, by standard procedures. The spectra of the 1, 2-cyclopentenofluorenes are identical with those of a series of hydrocarbons, obtained by Jacobs and co-workers in the dehydrogenation of cevine and jervine. A by-product of the reduction of fluorenone-1-to fluorene-1-carboxylic ...
