Özet
Different aliphatic and aromatic acyl phosphonates were synthesized using Arbuzov reaction and subjected to Oxo-Diels-Alder (ODA) reaction with 2,3-dimethyl-1,3-butadiene at -78 degrees C. AlCl3 was found the best catalyst to obtain the desired ODA products from acyl phosphonates in only 30min at low temperature, as compared to 100 degrees C-previously reported. The same reaction was repeated at room temperature but, instead of ODA, Wittig-type product was obtained. All the products were characterized by NMR spectroscopy and mass spectrometry. H-1,P-31 and C-13,P-31 couplings were observed in the NMR spectra.
