Abstract:Three acetphenol ester compounds were obtained through the reaction of acetic acid with methyl 4-hydroxybenzoate, methyl 4-hydroxy-3-methoxybenzoate and methyl 4-hydroxy-3,5-dimethoxybenzoate, respectively. The structure of the three acetphenol ester compounds was characterized by elemental analysis and X-ray single crystal diffraction. Methyl 4-acetoxybenzoate (2a) belongs to monoclinic crystal system, a space group C2/c with a=25.400(4) ?魡, b=5.9738(10) ?魡, c=12.746(2) ?魡, V=1928.5(6) ?魡3. Methyl 3-methoxy-4-acetoxybenzoate (2b) belongs to the monoclinic crystal system, a space group P-1P212121 with a=5.552 3(7) ?魡, b=12.761 0(17) ?魡, c= 15.374(2) ?魡, V=1089.3(2) ?魡3. Methyl 3,5-Dimethoxy-4-acetoxybenzoic acid (2c) belongs to monoclinic crystal system, a space group Pbca with a=18.020 7(13) ?魡, b=7.688 5(5) ?魡, c=18.232 6(13) ?魡, V=2526.2(3) ?魡3. The structures of these synthesized intermediates are all correct. |
