2-甲氧基苯基乙二醛水合物

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: SeO2 (12.4 g., 0.112 mol) was dissolved in 75 ml. of 95% ethanol by warming to 55°. o-Methoxyacetophenone (15.3 g., 0.102 mol) was added in one portion and the mixture refluxed 21 hours. The reaction mixture was treated with activated carbon, filtered over diatomaceous earth, and the filtrate stripped to yield to an oil, 23.2 g. The latter was distilled to yield purified title product, 8.4 g., bp 94°-96°/0.5 mm, which solidified on cooling. the mixture refluxed 21 hours The reaction mixture was treated with activated carbon filtered over diatomaceous earth to yield to an oil, 23.2 g The latter was distilled to yield purified title product, 8.4 g on cooling
