Abstract: The reproducible yield of 7-nitro-1,3-benzodioxane (2) from the reaction of 3-nitrophenol and 40% formaldehyde catalyzed by sulfuric acid is less than 1%[1]. By replacing formaldehyde with triformol, followed by treatment of the crude product with 10% NaOH solution, we have improved the yield to 12%. An orthogonal design experiment was carried out to optimize the conditions[2].
