A series of 2-substituted and 2,2-disubstituted 1,3-benzodioxoles have been synthesised by reaction of catechol and pyrogallol with corresponding aldehydes and ketones catalysed by montmorillonite KSF or K-10. The reactions are completed within 2.7–24 h to give satisfactory yields. Ketones give better yields than aldehydes, although highly sterically hindered ketones and diaryl ketones fail to react at all.
一系列2-取代和2,2-二取代的1,3-苯并二氧杂烯已经通过用相应的醛和酮催化反应成氟土矿 KSF 或 K-10与氢醌和苦味酸合成。反应在2.7到24小时内完成,产率令人满意。尽管高度立体障碍的酮和二芳基酮完全不反应,但酮的产率优于醛的产率。
