| Abstract: | The title compound (C24H30O5) was synthesized by the reaction of 4-methoxybenzaldehyde and dimedone in ionic liquid bmim+]BF-4]. Its structure was characterized by elemental analysis, IR, 1HNMR and X-ray single crystal diffraction. The crystal is of monoclinic, space group P21/n with a=0.887 77(14), b=1.154 5(2), c=2.100 6(4) nm, β=98.530(7)°, Mr=398.48, V=2.129 2(6) nm3, Dc=1.243 g/cm3, Z=4, μ (Mo Kα)=0.086 mm-1, F(000)=856, R=0.056 9, Rw=0.115 9. X-ray analysis reveals that the enol form ring adopts a half-chair conformation. In addition, there are intramolecular hydrogen bonds in the structure. |
