It is known that the ease of the 1,5 migration of groups in cyclopentadienes is associated with their acceptor power. On the basis of this and in view of the tendency of phosphonoacetic acid triester to react at the C=O group of ..cap alpha..-enols (Wittig-Horner reaction), the authors studied the reactions of phosphonoacetic acid trimethyl ester with cyclones. 2,5-Bis(methoxycarbonyl)-3,4-diphenylcyclopentadienone reacts with the sodium derivative of phosphonoacetic acid trimethyl ester with the formation of adducts in which the carbanion center of the reagent is linked to the C/sup 2/ atom of cyclopentadienone. The IR spectra were determined on a UR-10 spectrometer. The PMR spectra were recorded on Varian T-60 and Tesla BS-467A spectrometer, solvent CHCl/sub 3/ or CDCl/sub 3/, internal standard TMS.
