Arylidene Meldrum's acid is employed as a source of the aryl group and oxidant for the synthesis of 2-aryl-1H–benzimidazoles by a condensation reaction with 1,2-phenylenediamine in refluxing ethanol with good to high yields. Arylidene Meldrum's acids were also used as a source of the aryl group and oxidant for the synthesis of 2-aryl-1H-perimidines by a condensation reaction with 1,8-diaminonaphthalene
亚芳基 Meldrum 酸被用作芳基的来源和氧化剂,用于通过与 1,2-苯二胺在回流乙醇中的缩合反应合成 2-芳基-1H-苯并咪唑,收率良好至高。亚芳基 Meldrum 的酸也被用作芳基的来源和氧化剂,用于通过与 1,8-二氨基萘在回流乙醇中的缩合反应以高产率合成 2-芳基-1H-脒。
