We describe here the synthesis of several compounds that include intercalators such as naphthalimide or fluorene, linked to different systems of double and triple bonds. An unusual behaviour of the 9-fluorenylidenetriphenylphosphorane 9 with acetylenic carbonyl compounds, bath aldehyde or ketone, is also reported. The isolated products are the result of a [2+2] cycloaddition between the triple bond and the C=P double bond, unreported for acetylenic aldehydes or ketones. None or the compounds described have shown any interesting cytotoxic activity.
