A new type of unsaturated phosphonates 5 were synthesized by the Wittig-Horner reactions of bisphosphonylmethane 4 with 5-aryl-2(E),4(E)-pentadienal and 5-aryl-3-methyl-2(E), 4(E)-pentadienal. The structures of all new compounds prepared were characterized by H-1 NMR, P-31 NMR, C-13 NMR, IR spectra, MS and elemental analyses, one of them was determined by X-ray diffraction analysis.
