Cooperative action of hydrogen and halogen bonding in the reaction of 3-(3,5-di-tert-butyl-4-hydroxyphenyl)-1-phenylprop-2-en-1-one with HCl or HBr in alcohol medium under microwave irradiation (20 W, 80 °C, 10 min) allows the isolation of the haloetherification products (2S,3S)-3-(3-tert-butyl-5-chloro-4-hydroxyphenyl)-2-chloro-3-ethoxy-1-phenylpropan-1-one, C21H24Cl2O3, (2S,3S)-2-bromo-3-(3-tert-butyl-5-bromo-4-hydroxyphenyl)-3-methoxy-1-phenylpropan-1-one, C20H22Br2O3, and (2S,3S)-2-bromo-3-(3-tert-butyl-5-bromo-4-hydroxyphenyl)-3-ethoxy-1-phenylpropan-1-one, C21H24Br2O3, in good yields. Both types of noncovalent interactions, e.g. hydrogen and halogen bonds, are formed to stabilize the obtained products in the solid state.
在微波辐照(20 瓦,80 °C,10 分钟)下,3-(3,5-二叔丁基-4-羟基苯基)-1-苯基丙-2-烯-1-酮与 HCl 或 HBr 在醇介质中反应时,氢键和卤素键的协同作用使得卤醚化产物(2S、3S)-3-(3-tert-butyl-5-chloro-4-hydroxyphenyl)-2-chloro-3-ethoxy-1-phenylpropan-1-one, C21H24Cl2O3, (2S,3S)-2-bromo-3-(3-tert-butyl-5-bromo-4-hydroxyphenyl)-3-methoxy-1-phenylpropan-1-one,C20H22Br2O3 和 (2S,3S)-2-溴-3-(3-叔丁基-5-溴-4-羟基苯基)-3-乙氧基-1-苯基-1-丙酮(C21H24Br2O3),收率良好。两种非共价相互作用(如氢键和卤素键)的形成,使得到的产物在固态下稳定。
