3,3,6,6-tetramethyl-1,4-dioxane-2,5-dione

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Crude tetramethyl glycolide was prepared by direct liquid phase synthesis from 2-hydroxy-2-methylpropionic acid using m-xylene as the solvent and p-toluene sulfonic acid as the catalyst. The mixture was refluxed using a Dean-Stark tube to remove water. The mixture was refluxed to remove water
