摘要
以硒粉、硼氢化钠、苯腈、1,3-二氯丙酮为原料,合成了2-苯基-4-硒唑甲醛,考察了反应条件对收率的影响,最佳反应条件为:n(乌洛托品):n(2-苯基-4-氯甲基硒唑):n(乙酸)=1.6:1:15,回流反应6h,收率可达76.2%.产物结构经元素分析、IR、1H NMR及ESI-MS等方法进行了确证.
2-Phenyl-4-formylselenazole was synthesized from selenium, sodium borohydride, benzoni-trile and 1,3-dichloroacetone. The effects of the reaction conditions to the yield were checked. The optimal reaction conditions of the oxidation step were found as follows: n(hexamethylenetetramine) : n(2-phenyl-4-chloromethylselenazole) : n(acetie acid)=1.6 : 1 : 15, the reflux reaction time 6 hours. The total yield could reach 76.2%. The target compound was confirmed by elemental analysis, IR, ^1H NMR and ESI-MS.
