摘　　要：提出以胡椒基酸为原料,经1,3-二甲基-2-取代苯并咪唑盐与碲氢化钠发生还原-水解反应制备胡椒醛的新合成方法,对反应机理进行了讨论。Various methods for synthesis of piperonal were investigated. Piperonal was synthesized, using 3, 4-methylenedioxy benzoic acid as raw material, through the reduction-hydrolysis reaction of 1,3-dimethyl-2-substltuted benzimldazollum salt with sodium hydrogen teUufide. The melting point and IR spectra of the title compound were consistent with those reported in the literature. The reaction mechanism was also discussed.
